DESCRIPTION:Weiyao Ke(LANL) \n\nIn electron-ion collisions\, hadron produc
 tion receives sizable nuclear matter corrections. In the past\, calculati
 ons based on a phenomenologically modified DGLAP (mDGLAP) equation well d
 escribed these phenomena.  To elucidate the physics contained in the mDGL
 AP approach\, we performed a renormalization group analysis on the parton
  evolution in nuclear matter.\n\nWe find that in a dilute or fast-expandi
 ng medium\, radiative corrections to collinear observables are enhanced b
 y $\\ln \\left[E/(L\\mu_D^2)\\right]$. $E\, L\,\\mu_D$ are the jet energy
 \, medium size\, and the inverse scattering length in the medium. Multipl
 e medium-induced radiations are resummed by a set of partial differential
  equations with a surprising traveling-wave-like solution\, encoding part
 on energy loss effects. Despite the apparently different form\, these dif
 ferential equations are equivalent to a particular version of mDGLAP\, bu
 t are much simpler for practical applications and bear a clear physical p
 icture of the mechanism of medium modifications. Applications to studying
  the modified fragmentation in $eA$ collisions\, hadron quenching in high
 -energy $pA$ collisions\, and future improvements are discussed at the en
 d.

DESCRIPTION:Hee-Jong Seo (Ohio University)\n\nTitle:\nAccelerating expansi
 on of the Universe through DESI\n\nAbstract:\nOne of the most intriguing 
 questions in physics today is the nature of dark energy that is responsib
 le for the accelerated expansion of the Universe. Three-dimensional maps 
 of galaxies from spectroscopic galaxy surveys provide a giant laboratory 
 to test the nature of the Universe\, including dark energy\, in a way tha
 t is complementary to other cosmic surveys. DESI\, being the largest gala
 xy redshift survey up to date\, is currently preparing for the first-year
  cosmology analysis release in Summer 2023\, In this talk\, among the key
  science goals of DESI\,  I want to focus on the studies of two accelerat
 ed expansion phases of the Universe using DESI\, one today due to dark en
 ergy and the other\, cosmic inflation right after the Big Bang. For the f
 ormer\, I will show the first Baryon Acoustic Oscillation detection resul
 t using only the first two months of the DESI data. For the latter\, I wi
 ll discuss how we can fight the observational systematics using neural ne
 tworks and derive a tight constraint on inflation using the DESI Legacy s
 urvey.

DESCRIPTION:Zoltan Fodor (Penn State U.)\nTwenty years ago\, in an experim
 ent at Brookhaven National Laboratory\, physicists detected what seemed t
 o be a discrepancy between measurements of the muon's magnetic moment and
  theoretical calculations of what that measurement should be\, raising th
 e tantalizing possibility of physical particles or forces as yet undiscov
 ered. The Fermilab team has announced that their precise measurement supp
 orts this possibility. The reported significance for new physics is 4.2 s
 igma just slightly below the discovery level of 5 sigma. However\, an ext
 ensive new calculation of the muon's magnetic moment using lattice QCD by
  the BMW-collaboration reduces the gap between theory and experimental me
 asurements. The lattice result appeared in Nature on the day of the Fermi
 lab announcement. In this talk both the theoretical and experimental aspe
 cts are summarized with two possible narratives: a) almost discovery or b
 ) Standard Model re-enforced. Some details of the lattice calculation are
  also shown.

DESCRIPTION:Speaker: Bastien Carreres\n\nTitle: Growth-rate measurement wi
 th type Ia supernovae\n\nAbstract:\nMeasurements of the growth rate of st
 ructures have the potential to detect potential deviations from General R
 elativity. The growth rate can be measured using its link to the cosmolog
 ical velocity field. In the past decade\, the majority of growth-rate mea
 surements were performed indirectly by using redshift space distortions o
 n clustering. However\, due to a lack of statistics\, this method isn't p
 recise at low redshift. An efficient method to measure the growth rate at
  low redshift is to directly estimates velocities from redshift and dista
 nce indicators. Until today the statistics of SN Ia was too law to be use
 d in such analysis and galaxies were used as distance indicators. New gen
 eration of surveys will provide sufficient number of SN Ia to do the grow
 th-rate measurement. In this talk\, I will present our work on the growth
 -rate measurement using SN Ia simulation from the ZTF survey.

DESCRIPTION:Speaker: James Trussler (The University of Manchester)\n\nTitl
 e: JWST's first glimpse of the first galaxies\n \nAbstract:\nJWST has ush
 ered in a great new golden age of astronomy\, opening the possibility of 
 discovering and characterising primordial galaxies deep within the epoch 
 of reionisation (EoR). In this talk I will therefore highlight how JWST h
 as already begun to transform our understanding of the formation and evol
 ution of the first galaxies in the Universe. First\, I will discuss the f
 irst images and spectra taken by JWST - centred on the now-famous galaxy 
 cluster SMACS 0723 - which immediately demonstrated that intense star for
 mation and extreme nebular conditions are likely the norm\, rather than t
 he exception\, for galaxies in the EoR. Second\, I will discuss our searc
 h for EoR galaxies exhibiting two strong spectral breaks in their photome
 try\, providing evidence for evolved stellar populations in these galaxie
 s\, and thus enabling us to indirectly infer the epoch when the first gal
 axies began to form. Third I will introduce a set of photometric and spec
 troscopic diagnostics that I have developed to identify potential first g
 alaxy candidates\, i.e. chemically pristine Population III galaxies in th
 e EoR. Finally\, I will close by revealing whether any convincing Pop III
  candidates have been identified from the early Webb data.

DESCRIPTION:Varun Vaidya (U. of South Dakota) Even after 50 years of the f
 ormulation of the QCD Lagrangian\, a conceptual understanding of hadron s
 tructure starting from the microscopic theory remains elusive. A related 
 problem is the  calculation of  Parton Distribution functions(PDFs) which
  encode the partonic content of the hadron wavefunction. In this talk\, I
 'll propose a new approach towards unraveling this mystery by borrowing i
 deas from Quantum information science. We suggest that since a strongly c
 oupled bound state hadron is a complex system with numerous interactions 
 between its partons\, notions from complex systems\, statistical mechanic
 s\, and information theory can be elevated to a more central role in desc
 ribing its properties. In particular\, I will put  forward a possible eme
 rgent minimum free energy principle based on the quantum entanglement pro
 perties of partons making up  the bound state . As a first step\, I'll di
 scuss the success of this technique in describing the ground state spectr
 um and PDF of mesons and baryons in 1+1 D gauge theories and speculate on
  how these ideas can be applied to gauge theories in higher dimensions.

DESCRIPTION:Speaker: Roohi Dalal (Princeton)\nTitle: Cosmology from Cosmic
  Shear Power Spectra with Hyper Suprime-Cam Year 3 Data\n\nAbstract:\nThe
  Hyper Suprime-Cam (HSC) survey is the deepest Stage III weak lensing exp
 eriment\, going to ~26 mag with exquisite seeing. The depth and image qua
 lity achieved by HSC allow us to probe cosmology using weak lensing upto 
 high redshifts\, and the analyses serve as important preparatory studies 
 for the next generation of weak lensing surveys. I will discuss our const
 raints on cosmological parameters using weak lensing cosmic shear power s
 pectra measured from the Year 3 shear catalog of HSC. The shear catalog\,
  prepared by Li et al. 2022\, covers 416 square degrees of the northern s
 ky\, with a mean i-band seeing of 0.59 arcsec and an effective galaxy num
 ber density of 15 arcmin^-2. With an i-band magnitude limit of 24.5 mag\,
  and four tomographic redshift bins spanning 0.3<z<1.5\, we obtain a high
 -significance measurement of the cosmic shear power spectra in the multip
 ole range 300<\\ell<1800. I will describe our cosmological analysis\, inc
 luding the steps we take to prevent confirmation bias as well as our mode
 ling of various sources of systematic uncertainties. I will then discuss 
 our new constraint on the S8 parameter\, and how it informs our understan
 ding of the apparent 2-3 sigma tension between constraints on S8 from wea
 k lensing experiments and those from the CMB. Finally\, I will discuss on
 going and future work that can further shed light on the S8 tension\, inc
 luding an improved modeling of baryonic feedback at small scales.

DESCRIPTION:We discuss aspects of energy loss\, thermodynamics\, and runni
 ng coupling in small collision systems at RHIC and LHC.  The small system
  size correction to the opacity expansion energy loss increases the destr
 uctive LPM interference linearly with energy\, thus predicting a decrease
  in the suppression of high momentum particles above and beyond that just
  due to foreshortened path lengths.  Massless scalar thermal field theory
  in a box predicts significant changes to the pressure\, entropy density\
 , etc.\, which mimic the temperature-dependent behavior of thermal QCD\; 
 thus some part of the signal of QGP formation taken from thermodynamics m
 ight actually be due to geometry.  Despite the breaking of conformal inva
 riance by placing fields in a box\, the energy momentum tensor remains tr
 aceless unless we include running coupling corrections.  A toy model for 
 the finite system size corrections to the running coupling significantly 
 reduces the trace anomaly\, suggesting that current hydrodynamics simulat
 ions significantly under-predict eta/s in small systems.  We discuss a ne
 w regularization scheme\, denominator regularization\, which allows a fir
 st principles derivation of the small system size correction to the runni
 ng coupling in field theories and to critical exponents in condensed matt
 er physics.

DESCRIPTION:Since the introduction of the LaMET framework by Xiangdong Ji 
 a decade ago\, there has been a revolution in our ability to quantitative
 ly understand the internal structure of hadrons\, characterized by the ma
 trix elements of operators separated along the light cone.  In this talk\
 , I begin with describing an alternative framework\, that of pseudo-PDF\,
  employing short-distance factorization.  I then present a program of cal
 culations by the HadStruc collaboration to compute the one-dimensional di
 stributions of the nucleon\, including the isovector unpolarized and heli
 city PDFs and the transversity\, and of the pion. Notably\, I describe  r
 ecent calculations of the gluon contributions to nucleon structure.  I co
 nclude by exploring a combined analysis of lattice QCD calculations and e
 xperimental data in furthering our understanding of the internal structur
 e of nucleon and pion structure

DESCRIPTION:Charge Susceptibilities\, or charge fluctuations\, represent c
 ritical observables for characterizing the chemistry and equation of stat
 e of QCD matter. Unfortunately\, a heavy-ion collision traverses a wide s
 wath of the density-temperature plane\, and due to the short time scale c
 harge conservation restricts the degree to which fluctuations represent e
 quilibrium quantities. I will show how one can use charge correlations\, 
 binned by relative rapidity\, relative azimuthal angle\, and indexed by s
 pecies\, to not just constrain the susceptibilities\, but to extract thei
 r evolution in time throughout the collision. Additionally\, the ability 
 of such correlations to simultaneously constrain the charge diffusivity o
 f QCD matter will be presented. A detailed microscopic model of such corr
 elations is then compared to data from the STAR Collaboration at RHIC and
  from the ALICE Collaboration at the LHC. The prospects to quantitatively
  constrain fundamental properties of QCD matter are found to be very enco
 uraging.

DESCRIPTION:Abstract: Since the first positive measurement of the Lambda-h
 yperon global spin polarization in heavy-ion collisions by STAR in 2017\,
  the understanding of the nature of this phenomenon is one of the most in
 triguing challenges for the community. As relativistic fluid dynamics cel
 ebrates multiple successes in describing collective dynamics of the QCD m
 atter in such reactions\, the natural question arises whether the spin dy
 namics can also be modeled in such a framework. In this talk\, the motiva
 tion for and recent outcomes of the experimental hunt for the macroscopic
  footprints of quantum spin in the relativistic heavy-ion collisions will
  be presented and the theoretical challenges connected with formulating i

DESCRIPTION:Quantum materials are broadly distinguished by their unique ma
 croscopic phases\, which emerge as a result of electronic interactions ac
 ross many length scales. These emergent phases lead to functionalities wi
 th enormous technological potential\, such as high temperature\, supercon
 ductivity and multiferroicity\, but devising ways to manipulate their qua
 ntum behavior "on demand" for practical applications remains a major chal
 lenge. In this talk\, I will describe a methodology to engineer materials
  properties dynamically with ultrashort light pulses\, which results in n
 on-equilibrium states that often cannot be achieved \notherwise. We use i
 ntense\, tailored\, THz-frequency excitation to drive ions in the crystal
  lattice to large amplitudes and exploit nonlinearities to steer the vari
 ous degrees of freedom of the system. This approach provides a knob to tu
 ne electronic and magnetic interactions\, break symmetries\, and unlock n
 ew phases. I will highlight some recent experiments demonstrating the abi
 lity to optically control\, enhance\, and induce magnetism and ferroelect
 ricity in complex oxides. Interestingly\, the ultrafast dynamics of these
  driven systems gives way\, in some cases\, to metastable light-induced s
 tates persisting for "ultralong" times\, which form even well above the e
 quilibrium ordering temperature. Finally\, \nI will touch upon our curren
 t efforts of integrating atomic layer materials synthesis to enable the r
 ational design of non-equilibrium functionalities for next-generation qua
 ntum and ultrafast technologies.

DESCRIPTION:The electron's orbital moment has recently emerged as an impor
 tant degree of freedom which can be generated\, transported\, and used to
  control magnetic systems [1]. However\, its role in magnetism remains po
 orly understood. I will discuss surprising experimental observations reve
 aling a crucial role of the electron's orbital moment in ferromagnetism a
 nd elucidating a previously unrecognized connection between magnetism and
  unconventional superconductivity.\n\nOur magnetoelectronic measurements 
 of heterostructures based on ultrathin transition metal ferromagnets reve
 aled two separate magnetic order parameters: one associated with spin ord
 ering at the Curie point Tc1\, and another "anomalous" order parameter wi
 th a critical point Tc2 about 50K above the Curie temperature. Remarkably
 \, magneto-optical measurements are not sensitive to the anomalous contri
 bution\, suggesting that the origin of the latter is qualitatively differ
 ent from spin magnetism. X-ray magnetic circular dichroism (XMCD) measure
 ments show that the "anomalous" order parameter is associated with incipi
 ent orbital ferromagnetism whose signatures vanish below Tc2 without the 
 onset of ferromagnetic orbital ordering. Electric current applied to micr
 opatterned structures in this regime reveals that orbital magnetism is "h
 idden" but does not disappear below Tc2.\n\nI will show that these anomal
 ous behaviors are captured by a simple Hubbard model of orbital correlati
 ons among nearest neighbor sites in an ultrathin ferromagnetic layer\, le
 ading to the conclusion that orbital moments form an orbital liquid [2] -
  a long-range correlated orbital state that lacks ordering due to the geo
 metric orbital frustration\, analogous to quantum spin liquids formed by 
 frustrated spins and believed to hold the key to high-temperature superco
 nductivity [3]. In the studied orbital liquid\, orbital moments are ferro
 magnetically coupled\, which would be impossible for spin liquid due to s
 pin conservation. I will discuss the implications of these results for ou
 r understanding of the mechanisms of magnetism and for the emerging field
  of orbitronics.

DESCRIPTION:Abstract:\n \nThe Standard Model of particle physics has an em
 barrassing problem -- we cannot formulate it nonperturbatively. This come
 s from the difficulty of putting a chiral gauge theory on the lattice. On
 e of the important developments motivated by this question is the Ginspar
 g-Wilson (GW) relation\, which encodes how the anomalous chiral symmetry 
 "optimally" manifests on the lattice. \n \nOn the other hand\, developmen
 ts in condensed-matter have uncovered a deep connection between anomalies
  and topological insulators/superconductors. At the boundary of such topo
 logical materials\, you can have massless fermions with an anomalous symm
 etry. Domain-wall fermions used in lattice QCD simulations can be underst
 ood as a special case of this. Since domain-wall fermions are a solution 
 to the GW equation\, one may wonder -- can the GW relation and its soluti
 ons be generalized to other topological insulators and superconductors?\n
  \nIn this talk\, we will review the story of chiral fermions on the latt
 ice and the importance of the Ginsparg-Wilson relation. We will then disc
 uss how it can be generalized to boundary theories of various classes of 
 topological insulators and superconductors. Interestingly\, perturbative 
 and even some global anomalies (à la Witten) show up in this formalism in
  an elementary fashion from the Jacobian of the fermionic measure.\n \nBa

DESCRIPTION:Speaker: Nora Sherman (University of Michigan)\n\nWhen/Where: 
 2:00pm (ET)\, Dec. 07 / PHY 298\n\nTitle: Bright Mergers in a Dark Univer
 se: The New Searches for Optically Bright Gravitational Wave Progenitors\
 n\nAbstract:\nIn the new era of multi-messenger astronomy\, the mergers o
 f dead star remnants like neutron stars and black holes present vast oppo
 rtunities for both cosmological and astrophysical discovery. Mergers that
  produce optical emission provide a novel measurement of the Hubble Const
 ant that does not suffer from the same systematics present in other appro
 aches\, providing a potential avenue for relieving the Hubble Tension in 
 these measurements. While gravitational wave progenitors containing neutr
 on stars are best predicted (or known) to produce electromagnetically bri
 ght counterparts\, binary black hole mergers\, under complex conditions\,
  have the potential to do so as well\, and the discovery of such an optic
 ally bright merger would not only allow for a more rapid and statisticall
 y significant standard siren measurement of the Hubble Constant but would
  also introduce a new avenue for the astrophysical study of these mergers
 . With the fourth observing run (O4) the LIGO/Virgo/Kagra collaboration u
 nderway\, we are preparing for multitudes more data that will lead to the
 se discoveries. In this talk\, I will discuss the Dark Energy Survey Grav
 itational Wave group's approach to finding and studying these mergers and
  work toward and during O4 as well as dive into how binary black hole coa
 lescence might lead to an optically bright counterpart and my on-going wo
 rk on this front.\n\nZoom link: https://duke.zoom.us/j/274326260?pwd=bXdr

DESCRIPTION:The jets are powerful probes of quark-gluon plasma (QGP). When
  a jet loses energy to the QGP medium\, it induces the medium response re
 sembling a Mach-cone-like excitation. Investigating this jet-induced medi
 um response can help us to understand QGP properties. We have developed a
  2D jet tomography method to localize the initial jet positions and enhan
 ce the signal of the jet-induced diffusion wake-an unambiguous part of th
 e medium response. Additionally\, we employ a neural network to assist th
 is tomography. To further study the jet-induced diffusion wake\, we carry
  out the simulation of its 3D structure\, and investigate its sensitivity
  to QGP medium properties.  We also show that one can use the energy-ener
 gy correlators\, a novel jet substructure observable\, to investigate jet
 -induced medium response and the short distance structure of QGP in heavy
 -ion collisions.\n\nNOTE: This talk will actually be a Triangle Nuclear T
 heory Seminar.

DESCRIPTION:Speaker: Xiangchong Li (Carnegie Mellon University)\n\nTitle: 
 Precision Weak Gravitational Lensing: From Image Analysis to Cosmology In
 ference\n\nAbstract:\nWeak gravitational lensing shear introduces a subtl
 e yet consistent distortion in the images of distant galaxies\, caused by
  the mass that lies in between\, making it an indispensable tool for mapp
 ing dark matter distribution and understanding the universe's expansion. 
 The Stage-IV weak-lensing surveys will measure the weak-lensing shear acr
 oss billions of galaxies with unprecedented precision\, necessitating our
  measurement techniques to be refined to achieve less than one percent sy
 stematic error. This presentation will kick off with a concise overview o
 f weak-lensing cosmology analysis using data from the Hyper Suprime-Cam (
 HSC) survey. Following this\, I will present a newly developed analytical
  approach designed for the rapid and accurate measurement of shear distor
 tion in galaxy images. Additionally\, I will discuss potential advancemen
 ts and applications of this approach for future explorations.

DESCRIPTION:Shailesh Chandrasekharan (Duke U.) Asymptotically free quantum
  field theories (AFQFT) emerge non-perturbatively in the continuum despit
 e the infinities that are plagued in perturbative calculations. Wilson's 
 RG provides a framework to understand this feature of AFQFT starting from
  a lattice regularization\, which however begins with the assumption that
  the local Hilbert space on the lattice is infinite dimensional so that t
 he UV fixed point is preserved. However\, recent effort in formulating th
 ese theories on a quantum computer forces one to look for lattice theorie
 s with a finite local Hilbert space. We refer to this as the "qubit regul
 arization" of a QFT. Does the finite local Hilbert space necessarily dest
 roy the UV fixed point\, or can it be recovered via RG? Recent results su
 ggest that the latter is true at least in some cases\, where the AFQFT ar
 ises at a quantum critical point in a theory with a finite local Hilbert 
 space. However\, the RG flow is quite exotic in these cases. We will use 
 the well-known BKT transition as an example to show this non-trivial RG f
 low.\n \nThe talk is based on the following recent paper:\n \nhttps://jou

DESCRIPTION:Quantum materials represent a broad class of systems whose exp
 erimental response relies on uniquely quantum aspects such as entanglemen
 t\, Berry phases\, and electronic correlations. Modeling of such material
 s presents challenges related to a variety complex behaviors that manifes
 t at different energy scales. In this field\, first-principles approaches
  often provide a vital bridge between experiments and theoretical models.
  In this talk\, I will introduce our numerical strategies for systematica
 lly building low-energy models with local charge\, spin\, and orbital deg
 rees of freedom of arbitrary complexity. I will discuss the insights that
  these methods have yielded for layered vdW materials\, in which spin-orb
 it coupling induces strongly anisotropic and competing magnetic interacti
 ons. I will also discuss preliminary work on extending these methods to t
 reat (i) spin-lattice coupling\, and (ii) dynamical effective Hamiltonian
 s for modeling non-linear responses in quantum materials\, and the breadt
 h of opportunities for non-linear spectroscopy.

DESCRIPTION:As cosmic microwave background (CMB) photons propagate through
  the Universe\, their interactions with matter imprint various properties
  of the matter onto the CMB. These imprints can probe otherwise difficult
  to measure baryons such as the ionized gas around galaxies\, which is to
 o cool to emit X-rays and does not have optical/IR tracer light (i.e. sta
 rs). Patchy screening\, the net effect of CMB photons Thomson scattering 
 into and out of the line of sight\, can directly probe the density profil
 e of this gas. Measuring this effect does not require redshift informatio
 n and thus is complementary to other gas probes like the thermal and kine
 matic Sunyaev-Zel'dovich effects. In this talk\, I will introduce a new p
 atchy screening estimator we have derived that is robust to biases from l
 ensing and extragalactic foregrounds. I will then describe our analysis u
 sing this new estimator with data from the Atacama Cosmology Telescope an
 d unWISE galaxy catalog to measure patchy screening at >7 sigma significa
 nce\, the first detection of the effect.  Our measurement of the average 
 gas density profile around unWISE galaxies provides further evidence that
  the circumgalactic gas is more extended than the underlying dark matter 
 distribution and\, with further modeling\, has the power to constrain bar
 yonic feedback models\, a major uncertainty in hydrodynamical simulations
  and optical weak lensing analyses. Finally\, I will present detection fo
 recasts for future CMB and large-scale structure surveys\, including CMB-
 S4 and Rubin LSST\, which show patchy screening will be a powerful probe 
 of small-scale baryonic physics and cosmological parameters.

DESCRIPTION:Difference Image Analysis (DIA) is a primary enabling techniqu

  and sky background generally vary with time and across the field of view
  for astronomical imaging data acquired through optical or nearinfrared t
 elescopes. These variations necessitate the homogenization of observed im
 ages using DIA to accurately measure the brightness of stellar explosions
  uncovered by the timedomain\nsurveys. In my talk\, I will review the fun
 damental concepts of DIA and the prevalent methods employed in time-domai
 n community\, with a particular emphasis on our novel SFFT algorithm. The
  SFFT method can enable accurate image differencing in Fourier space with
  remarkable computational advancement. I will show some existing applicat
 ions of SFFT method in time-domain surveys\, such as the DECam program DE
 SIRT in concert with the DESI operation for intermediate-redshift transie
 nts. Furthermore\, I will highlight a transient\nsearch framework we deve
 loped for JWST NIRCam/NIRISS observations and discuss our upcoming JWST C

 nique astrophysical information that is not accessible using either surve
 y alone. In this talk\, I will present recent results obtained by combini
 ng CMB data from the South Pole Telescope SZ (SPT-SZ) survey and LSS data
  from the Dark Energy Survey (DES). I will discuss some of the challenges
  we face when performing such cross-survey analyses and introduce Agora\,
  a simulation set designed specifically for analyses involving both CMB a

DESCRIPTION:In this talk\, I will present a novel framework for modeling t
 he weak lensing source galaxy redshift distribution and galaxy intrinsic 
 alignment via a shared luminosity function. In the context of LSST Year 1
  and Year 10 cosmic shear analysis\, I demonstrate the significant impact
  of the luminosity function on source galaxy redshift distributions and i
 ntrinsic alignment contamination. I establish the influence of Schechter 
 luminosity function parameters on the redshift distribution of a magnitud
 e-limited sample and show the effects of marginalizing over these paramet
 ers in intrinsic alignment modeling. I forecast how this joint modeling a
 pproach affects cosmological parameter constraints\, finding that it yiel
 ds constraints comparable to standard analyses while mitigating potential
  biases from incorrectly fixed luminosity function parameters. I highligh
 t the specific impact of the luminosity function shape on the cosmic shea
 r data vector and discuss the method's potential for modeling generic sel
 ection functions and extending to a 3x2pt analysis with galaxy bias incor
 poration. While focused on LSST cosmic shear\, this framework is broadly 
 applicable to weak lensing surveys.

DESCRIPTION:The Legacy Survey of Space and Time (LSST) will observe over 1
 0^6 transients per year\, increasing the number of yearly discovered tran
 sients by a factor of 100. With scarce spectroscopic resources\, an expec
 ted ~1% will be followed up spectroscopically\, despite being necessary f
 or probing supernova progenitor physics and accurately estimating cosmolo
 gical parameters. Due to the incoming immense quantity of transient sourc
 es\, we require a method to determine what subset of the discovered super
 novae should be investigated further. I present the LSST Spectroscopic Re
 commendation System which adapts and implements the Recommendation System
  for Spectroscopic Follow-up (RESSPECT) to select the most scientifically
  useful supernovae. This pipeline will aid in rapid follow-up observation
 s of interesting transient objects and use their spectra to uncover trans
 ient physics and optimize cosmological inference by creating a more pure 
 training sample of type Ia supernovae.

DESCRIPTION:X-ray measurements of the Intracluster Medium (ICM) reveal the
  delicate balance between gravitational processes and AGN/stellar feedbac
 k that shape the formation and growth of Galaxy Clusters. Spatially-resol
 ved radial profiles of ICM density\, thermodynamics\, and metallicity as 
 a function of redshift allow us to probe the self-similarity of cluster e
 volution\, resolve the history of cosmic enrichment in the Universe\, and
  help constrain cosmological parameters. However\, extending these measur
 ements to the highest redshifts pushes us into a regime where even deep o
 bservations with current flagship X-ray observatories are challenged\, as
  we attempt to measure source signals on par with the levels of astrophys
 ical and instrumental backgrounds. In this talk\, I will present a genera
 l\, new forward-modeling approach to the analysis of Chandra and XMM-Newt
 on observations that is proving highly effective\, and which can set the 
 standard of approaches that may be directed towards the analysis of obser
 vations made using the next generation of X-ray telescopes. I will detail
  our efforts to expand the joint X-ray coverage of known clusters at high
 -z\, and highlight the application of our analysis methods to ACT-CL J012
 3.5-0428 at z=1.51\, the highest redshift\, dynamically relaxed\, cool co
 re galaxy cluster discovered to date.

  parity-violations in the LSS of the Universe. If physical in origin\, th
 is could point to novel physics during the epoch of inflation. In this tw

DESCRIPTION:Altermagnets\, a new class of magnetic systems that combine ch
 aracteristics of both conventional ferromagnets and antiferromagnets\, ha
 ve recently attracted significant attention.  These collinear compensated
  magnets exhibit spin-split bands\, even in the absence of spin-orbit cou
 pling\, offering exciting prospects for applications in antiferromagnetic
  spintronics due to their lack of stray fields\, low damping and fast swi
 tching times. In this talk\, I will introduce altermagnets from a symmetr
 y-based perspective using ideas from Landau theory. Starting from the non
 relativistic limit\, this Landau theory goes beyond a conventional magnet
 ic analysis by including spin-space symmetries\, providing a simple frame
 work for understanding the key features of this family of materials. We f
 ind a set of multipolar secondary order parameters connecting existing id
 eas about the spin symmetries of these systems\, their order parameters\,
  and the effect of nonzero spin-orbit coupling. We account for several fe
 atures of candidate altermagnets such as MnF2\, MnTe\, and CuF2 that go b
 eyond symmetry alone\, relating the order parameter to key observables su
 ch as magnetization\, anomalous Hall conductivity\, and magnetoelastic an
 d magneto-optical probes. Finally\, I will discuss how our framework can 
 be generalized to a broader class of magnetic systems in the zero spin-or
 bit coupling limit\, as well as potentially to noncolinear magnetic struc
 tures.

DESCRIPTION:Heat transport investigations can reveal information about pho
 non dynamics and collective transport regimes in an insulator. In this ta
 lk\, I will discuss the insights and implications of the features observe
 d in the thermal transport of two representative perovskite-type complex 
 oxides\, SrTiO3 and BaBiO3. The first compound has gathered fundamental r
 esearch efforts across different topics\, such as superconductivity\, the
 rmoelectricity\, and ferroelectricity [1-2]. Thermal transport in single 
 crystalline SrTiO3 revealed the presence of the Poiseuille flow of phonon
 s at low temperatures and a high-temperature diffusivity approaching the 
 Planckian limit (τ=ℏ/kBT) [3]. The findings pointed to the role of the la
 ttice degrees of freedom and specific phonon modes in setting and manipul
 ating the heat conduction profile. The second one\, BaBiO3\, is the paren
 t compound of the first high-Tc superconductor without transition metal i
 ons. Its undoped insulating phase has an origin yet to be understood. Our
  very recent investigations of thermal conductivity in high-quality singl
 e crystals of BaBiO3 revealed an efficient suppression of heat transfer a
 t high temperatures and a glass-like behaviour at low temperatures\, sugg
 esting an exceptionally high anharmonicity which could be at the base of 
 phonon-mediated emerging phenomena [4]. \n\nREFERENCES\n1.      X. Lin et

DESCRIPTION:The accelerated expansion of the Universe was first observed a
 lmost 30 years ago using Type 1a supernovae (SN1a) as distance indicators
 . Since then\, the Hubble-Lemaître diagram has been populated by many exp

  measurements of the Baryon Acoustic Oscillations and the Cosmic Microwav
 e Background\, they now hint for an evolving dark energy. \nThese differe
 nt compilations use a common set of low-redshift supernovae from various 
 instruments with their own calibrations and completeness. The Zwicky Tran
 sient Facility (ZTF) will change this landscape by providing\, for the fi
 rst time\, a uniform set of nearby supernovae over the whole northern sky
 . \nIn this talk I will introduce ZTF and its newest SN data release (DR2
 ) which includes more than 2000 nearby SN1a\, well-sampled\, and spectros
 copically classified between March 2018 and December 2020. \nI will then 
 show our progress in photometric calibration to enable cosmological analy
 ses. I will focus mostly on the so called relative « ubercalibration » to
  improve survey uniformity.

DESCRIPTION:I will summarize recent work that aims to blend standard pheno
 menological approaches of \nTMD factorization and evolution with the goal
  of identifying and extracting nonperturbative hadronic structure. \nI wi
 ll argue that certain constraints are needed in order to maintain a parto
 n model interpretation while at the same time \nincluding a consistent tr
 eatment of evolution and perturbation theory.  Some early implementations
  will be shown\, and future directions will be summarized\, particularly 
 with regard to spin dependent TMD pdfs and fragmentation functions.

DESCRIPTION:Astrophysics and cosmology have entered an era of rich dataset
 s from both ground- and space-based observations. This advancement enable
 s compelling studies of galaxy evolution using techniques such as weak gr
 avitational lensing (WL) and spectroscopy.\nOn one side\, we leverage the
  JWST's crystal-clear vision and its cutting-edge instrument\, NIRCam\, t
 o study both dark and visible matter distributions in the COSMOS-Web fiel
 d using WL. Striking WL mass maps from the JWST COSMOS can reveal compell
 ing evidence of the complex interplay between baryonic and dark matter di
 stributions. \nOn the other side\, we utilize ground-based telescope data
  and spectroscopy to investigate the environments of Ultra-Compact Massiv
 e Galaxies (UCMGs)\, aiming to enhance our understanding of their formati
 on and evolution of these objects.

DESCRIPTION:The nucleon mass\, mN\, is a defining scale in Nature.  In fac
 t\, one understands the origin of almost all mass that is visible in the 
 Universe if one grasps the source of mN.  In modern high-energy physics\,
  approximately 98% of mN is expected to be generated by Standard Model st
 rong interactions\, i.e.\, to emerge from quantum chromodynamics (QCD).  
 The small remainder owes to Higgs boson couplings into QCD.  This present
 ation will present a perspective on these features of the Standard Model 
 strong interactions\, draw links to the emergence of hadron mass and stru
 cture\, and illustrate the connections via a unified set of parameter-fre
 e predictions for pion\, kaon\, nucleon electromagnetic and gravitational
  form factors.

DESCRIPTION:T he Vera C. Rubin Observatory Legacy Survey of Space and Time
  (Rubin LSST) is expected to achieve its first system light by late 2025.
  An initial data preview\, drawn from early commissioning phases\, is set
  for 2025-26\, exciting the scientific community as they prepare to explo
 re the Rubin LSST data. In this context\, we have been working on develop
 ing the DESC Time Domain (TD) pipeline with a focus on SNIa cosmology and
  dark energy estimation. In this work\, I present a rigorous cosmology an
 alysis with type Ia supernova performed with the DESC TD pipeline and stu
 dy the improvement from using a photometrically classified SNIa sample\, 
 and with host galaxy photo-z availability over cosmology results from spe
 ctroscopically obtained redshift 'only' SNIa sample. We use two different
  SN datasets: the ELAsTiCC (Extended LSST Astronomical Timeseries Classif
 ication Challenge) and the PLAsTiCC (Photometric LSST Astronomical Time-S
 eries Classification Challenge) supernova sample [2210.07560]. For identi
 fying non type Ia contaminations\, we use a photometric classifier\, SCON
 E (Supernova Classification with a Convolutional Neural Network). We show
  that with the use of photometric SNIa sample there is a significant impr
 ovement in dark energy estimation quantified via the Figure of Merit (FoM
 )\, over spectroscopic only SNIa sample. More details on the analysis and
  results shall be shared during the talk\, as the analysis is not yet com
 plete.
