DESCRIPTION:Topic: Dynamics of stellar binaries in nuclear star clusters\n
 \nSpeakers: Mark Dodici\, University of Toronto\n\nMore: https://www.ias.e
 du/sns/events/institute-advanced-study-astrophysics-seminar-153\n\nBinary 
 stars in the central parsecs of galaxies are involved in the\nproduction o
 f several modern astronomical phenomena\, including\nhypervelocity stars\,
  repeating partial tidal disruption events\, and\ndust-enshrouded objects 
 around Sgr A*. I present an overview of some\nkey aspects of the dynamical
  evolution of these binaries. In\nparticular\, I discuss recent theoretica
 l results suggesting that up to\nhalf of the stellar binaries in the centr
 al parsec of the Milky Way\nshould shrink to near-contact separations over
  their main sequence\nlifetimes. I then consider how the gravitational pot
 ential induced by\nan active galactic nucleus disk may sculpt this populat
 ion. Finally\, I\nattempt to connect these theories to observational puzzl
 es surrounding\nsome of the binary-related phenomena listed above.

DESCRIPTION:Topic: Theory for innovative cosmological tests of dark matter-
 baryon interactions \n\nSpeakers: Yacine Ali-Haimoud\, New York University
 \n\nMore: https://www.ias.edu/sns/events/institute-advanced-study-astrophy
 sics-seminar-140\n\nAmong many things\, dark matter could be made of new f
 undamental or\ncomposite particles\, which may feebly interact with nuclei
  or\nelectrons (“baryons”)\, as well as with themselves. Cosmological\nobs
 ervables are a promising avenue to test such interactions\, and are\ncompl
 ementary to direct-detection experiments\, in particular for\nprobing rela
 tively light dark matter particles. In this talk I will\nmotivate two proj
 ects to build theoretical tools for innovative and\nhigher-sensitivity cos
 mological tests of dark matter interactions --\nin the hopes to recruit he
 lp in finishing them! In Project 1\, I\npropose to expand and implement a 
 new framework allowing us to study\ndark matter- baryon interactions and d
 ark matter self-interactions\nsimultaneously and self-consistently: the Bo
 ltzmann-Fokker-Planck\n(BFP) formalism\, which I introduced in arXiv:1811.
 09903. The goal is\nto expand the BFP framework to incorporate dark matter
 \nself-interactions with arbitrary strengths\, and implement it into the\n
 Boltzmann code CLASS. In Project 2\, I motivate quantifying a\ncompletely 
 novel signature of dark matter-baryon scattering\, namely\nnon-Gaussianity
  in the Cosmic Microwave Background (CMB) arising from\nthe non-linearity 
 of the dark matter-baryon momentum-exchange rate.\nThis idea has similarit
 ies with a previous study my former student\nJensen and I conducted on pri
 mordial black holes\, which I will\nbriefly highlight.

DESCRIPTION:Topic: Rethinking about gravitational instability as a planet f
 ormation scenario\n\nSpeakers: Cristiano Longarini\, University of Cambrid
 ge\n\nMore: https://www.ias.edu/sns/events/institute-advanced-study-astrop
 hysics-seminar-141\n\nThe ubiquity of substructures in protoplanetary disc
 s has opened\ndebate regarding the alignment of planet formation timescale
 s with\nprotostellar disc evolution. Under the hypothesis of the planetary
 \ninterpretation\, a robust conclusion is that a substantial part of the\n
 planet formation process must overlap with the time when protostellar\ndis
 cs are likely to be young and\, possibly\, gravitationally unstable.\nHist
 orically\, gravitational instability has been proposed as a pathway\nfor p
 lanetary formation. However\, it lost favour due to the higher\nlikelihood
  of forming stellar companions rather than planets.\nNevertheless\, recent
 ly\, this scenario has gained new interest\, when\nthe synergy between gra
 vitational instability and dust dynamics is\nconsidered.\n\nIn this talk\,
  I will discuss the interplay between dust dynamics and\ngravitational ins
 tability. Gravitational instability is responsible\nfor the formation of a
  large scale spiral structure\, that efficiently\ntraps dust. There\, the 
 dust concentration can be so high that it\nbecomes unstable\, possibly col
 lapsing into Earth-mass objects. We\nanalytically characterise this behavi
 our\, and we confirm it through\nnumerical simulations\, showing that plan
 etary cores at large radii can\nbe efficiently formed in young protostella
 r discs.

 minar-143\n\nContinual improvements to our observational capabilities prom
 ise a\nwealth of data from binary neutron star systems in the coming years
 \nand decades\, which will find broad applications across several fields\n
 of physics. However\, the current generation of models for interpreting\nt
 hese events contain uncertainties and systematic errors that make\nthem un
 suitable for future events. In this talk\, I will discuss how\nsome of the

 more efficient computational techniques and more\naccurate numerical metho

DESCRIPTION:Topic: Which Microphysics Matters? The Case for Dust Dynamics\n
 \nSpeakers: Nadine Soliman\, Institute for Advanced Study\n\nMore: https:/
 /www.ias.edu/sns/events/institute-advanced-study-astrophysics-seminar-144
 \n\nAbstract: Numerical simulations of galaxies and the interstellar\nmedi
 um are now reaching resolutions where small-scale physical\nprocesses can 
 be resolved directly. This raises a natural question:\nwhich pieces of mic
 rophysics must be modeled explicitly in order to\ncapture the behavior of 
 astrophysical systems? In this talk I will\nargue that dust provides a par
 ticularly natural place to begin. Dust\ngrains interact simultaneously wit
 h radiation\, thermal balance\,\nchemical networks\, and gas dynamics\, pr
 ocesses that are critical to\nthe evolution of astrophysical environments.
  Yet in most simulations\ndust is assumed to remain perfectly coupled to t
 he gas\, reducing it to\na passive source of opacity and erasing its dynam
 ical role.\n\nUsing a combination of simulations and analytical arguments\
 , I will\npresent work that relaxes this assumption and follows dust as a
 \ndynamically distinct component. I consider several environments\,\ninclu
 ding AGN-driven winds\, star-forming molecular clouds\, and\nmagnetized du
 sty plasmas. In each case\, allowing dust to move relative\nto the gas pro
 duces qualitative changes that are absent when dust and\ngas are assumed t
 o move together. These include modifications to the\nstructure of radiatio
 n-driven outflows\, systematic effects on the\ncomposition and efficiency 
 of star formation\, and new pathways for\nseeding magnetic fields in the e
 arly Universe.\n\nTaken together\, these results illustrate how grain-scal
 e dust physics\npropagates upward to shape the large-scale structure and e
 volution of\nastrophysical systems.

 ic\nregimes\, governing key processes in diverse laboratory\, space\, and
 \nastrophysical environments. Understanding these systems requires\nnumeri
 cal models with varying levels of physical fidelity\, including\nmagnetohy
 drodynamic (MHD)\, multi-moment multifluid\, and\nparticle-in-cell (PIC) a
 pproaches\, as well as combined methods such as\nhybrid-PIC and adaptively
  embedded particle-in-cell (MHD-AEPIC)\nmodels. These approaches enable us
  to capture multiscale dynamics and\na broad range of plasma processes.\n
 \nIn this talk\, I will present several examples that connect plasma\ndyna
 mics across scales using different modeling approaches\, including\nlocal 
 simulations of magnetic reconnection and turbulence\, as well as\nglobal s
 tudies of star–planet interactions in our solar system and\nbeyond. I will
  also demonstrate how modern machine learning techniques\ncan be leveraged
  to incorporate kinetic physics into fluid models\,\nenabling them to repr
 oduce kinetic simulation results without\nexplicitly resolving phase-space
  dynamics.

DESCRIPTION:Topic: Inside Astronomically Realistic Black Holes\n\nSpeakers:
  Andrew Hamilton\, University of Colorado Boulder\n\nMore: https://www.ias
 .edu/sns/events/institute-advanced-study-astrophysics-seminar-147\n\nI wil
 l use a real-time general relativistic Black Hole Flight\nSimulator to sho
 w what really happens inside astronomically realistic\nblack holes. The in
 ner horizon of a rotating black hole is the most\nviolent place in the Uni
 verse\, easily reaching and surpassing energy\ndensities attained in the B
 ig Bang. What does Nature do at this\nextraordinary place?

DESCRIPTION:Topic: Kink Instability and Its Associated Turbulence in Astrop
 hysical Jets\n\nSpeakers: Hui Li\, Los Alamos National Laboratory\n\nMore:
  https://www.ias.edu/sns/events/institute-advanced-study-astrophysics-semi
 nar-149\n\nAstrophysical jets driven by black holes are thought to undergo
  kink\ninstabilities due to the large current carried by such jets.\nDissi
 pation of magnetic energy through kink instabilities has been\nsuggested t
 o account for the high-energy radiation (often in flaring\nfashion) up to 
 many TeVs. In recent years\, galactic microquasars (such\nas SS 433) have 
 generated a lot of interests\, given its high-energy\ngamma-ray radiation 
 (up to 100s TeV\, potentially to PeV) from their\njets/lobes. Furthermore\
 , in the case of SS433\, polarized X-ray\nemissions with spatially (quasi-
 )resolved polarization angle and\ndegree were reported by IXPE. The high d
 egree of polarization implies\nlarge-scale (~ several parsecs) coherent ma
 gnetic fields. In this\ntalk\, we will present 3D magnetohydrodynamic (MHD
 ) studies of kink\ninstabilities in jets and how they produce the polariza
 tion properties\nof jets.  The properties of kink-driven turbulence will b
 e described\nand compare with the properties of Alfvenic turbulence. Parti
 cle\nacceleration in kink-driven turbulence will be presented as well. We
 \nwill end with discussing possible implications for astrophysical jets\na
 nd lobes.

DESCRIPTION:Topic: Magnetospheric Accretion and Ejection\n\nSpeakers: Zhaoh
 uan Zhu\, Institute for Advanced Study\n\nMore: https://www.ias.edu/sns/ev
 ents/institute-advanced-study-astrophysics-seminar-150\n\nMagnetospheric a
 ccretion is a universal process occurring in\nmagnetized astronomical obje
 cts\, ranging from neutron stars and white\ndwarfs to young stars (YSOs) a
 nd planets. In the context of neutron\nstars\, this process is linked with
  phenomena such as X-ray pulsars and\nultra-luminous X-ray sources (ULXs).
  For YSOs\, it results in\nultraviolet (UV) excess and atomic emission lin
 es. Despite the wide\nvariance in the observation energy range\, the under
 lying physical\naccretion process exhibits many similarities\, primarily d
 ue to the\ngoverning role of magnetic fields. Understanding these dynamica
 l\nprocesses is essential for interpreting observational data and sheds\nl
 ight on the impact of accretion on star/planet evolution. We have\ncarried
  out first-principle three-dimensional magnetohydrodynamic\n(MHD) simulati
 ons to study magnetospheric accretion. I will discuss\nphysical insights g
 ained from these simulations\, which include\nfilamentary accretion due to
  the interchange instability\, magnetic\nbubbles similar to MAD disks\, st
 ar-disk torque\, field inflation\, field\nreconnection\, and episodic outf
 lows. Finally\, implications on\nexoplanets demographics will be discussed
 .
