Inferring the Morphology of Stellar Distribution in TNG50: Twisted and Twisted-Stretched shapes
Razieh Emami, Lars Hernquist, Charles Alcock +9
We investigate the morphology of the stellar distribution in a sample of Milky Way (MW) like galaxies in the TNG50 simulation. Using a local in shell iterative method (LSIM) as the…
A Holistic Review of a Galactic Interaction
Douglas Grion Filho, Kathryn V. Johnston, Eloisa Poggio +3
Our situation as occupants of the Milky Way (MW) Galaxy, bombarded by the Sagittarius dwarf galaxy, provides an intimate view of physical processes that can lead to the dynamical h…
Orbital Torus Imaging: Using Element Abundances to Map Orbits and Mass in the Milky Way
Adrian M. Price-Whelan, David W. Hogg, Kathryn V. Johnston +9
Many approaches to galaxy dynamics assume that the gravitational potential is simple and the distribution function is time-invariant. Under these assumptions there are traditional…
Active Galactic Nucleus Feedback in an Elliptical Galaxy with the Most Updated AGN Physics: Parameter Explorations
Zhiyuan Yao, Feng Yuan, Jeremiah P. Ostriker
In a previous work, we have proposed a sub-grid model of active galactic nucleus (AGN) feedback by taking into account the state-of-the-art AGN physics, and used that model to stud…
Mapping the tilt of the Milky Way bulge velocity ellipsoids with ARGOS and DR2
Iulia T. Simion, Juntai Shen, Sergey E. Koposov +4
Until the recent advent of Data Release 2 (DR2) and deep multi-object spectroscopy, it has been difficult to obtain 6-D phase space information for large numbers of stars be…
Separatrix Divergence of Stellar Streams in Galactic Potentials
Tomer D. Yavetz, Kathryn V. Johnston, Sarah Pearson +2
Flattened axisymmetric galactic potentials are known to host minor orbit families surrounding orbits with commensurable frequencies. The behavior of orbits that belong to these orb…
Measuring the vertical response of the Galactic disc to an infalling satellite
Eloisa Poggio, Chervin F. P. Laporte, Kathryn V. Johnston +3
Using N-body simulations of the Milky Way interacting with a satellite similar to the Sagittarius dwarf galaxy, we quantitatively analyse the vertical response of the Galactic disc…
Discovery of Magellanic Stellar Debris in the H3 Survey
Dennis Zaritsky, Charlie Conroy, Rohan P. Naidu +9
We report the discovery of 15 stars in the H3 survey that lie, in projection, near the tip of the trailing gaseous Magellanic Stream (MS). The stars have Galactocentric velocities…
MOSEL and IllustrisTNG: Massive Extended Galaxies at z=2 Quench Later Than Normal-size Galaxies
Anshu Gupta, Kim-Vy Tran, Annalisa Pillepich +4
Using the TNG100 (100 Mpc)^3 simulation of the IllustrisTNG project, we demonstrate a strong connection between the onset of star formation quenching and the stellar size of galaxi…
The GALAH+ Survey: Third Data Release
Sven Buder, Sanjib Sharma, Janez Kos +44
The ensemble of chemical element abundance measurements for stars, along with precision distances and orbit properties, provides high-dimensional data to study the evolution of the…
Characterizing the Circumgalactic Medium of the Lowest-Mass Galaxies: A Case Study of IC 1613
Yong Zheng, Andrew Emerick, Mary E. Putman +3
Using 10 sightlines observed with the Hubble Space Telescope/Cosmic Origins Spectrograph, we study the circumgalactic medium (CGM) and outflows of IC1613, which is a low-mass ($M_*…
A Framework for Multiphase Galactic Wind Launching using TIGRESS
Chang-Goo Kim, Eve C. Ostriker, Drummond B. Fielding +6
Galactic outflows have density, temperature, and velocity variations at least as large as that of the multiphase, turbulent interstellar medium (ISM) from which they originate. We…
The critical dark matter halo mass for Population III star formation: dependence on Lyman-Werner radiation, baryon-dark matter streaming velocity, and redshift
Mihir Kulkarni, Eli Visbal, Greg L. Bryan
A critical dark matter halo mass () for Population III (Pop III) stars can be defined as the typical minimum halo mass that hosts sufficient cold dense gas required f…
Radiative feedback for supermassive star formation in a massive cloud with H2 molecules in an atomic-cooling halo
Yuya Sakurai, Zoltán Haiman, Kohei Inayoshi
Recent three-dimensional cosmological simulations of protogalaxy formation have suggested that supermassive stars (SMSs) can form in gas clouds in which H cooling is suppressed…
IQ Collaboratory II: The Quiescent Fraction of Isolated, Low Mass Galaxies Across Simulations and Observations
Claire M Dickey, Tjitske K Starkenburg, Marla Geha +10
We compare three major large-scale hydrodynamical galaxy simulations (EAGLE, Illustris-TNG, and SIMBA) by forward modeling simulated galaxies into observational space and computing…
The Cosmic Ultraviolet Baryon Survey (CUBS) II: Discovery of an H-Bearing DLA in the Vicinity of an Early-Type Galaxy at z = 0.576
Erin Boettcher, Hsiao-Wen Chen, Fakhri S. Zahedy +18
We report the serendipitous detection of an H-bearing damped Lyman- absorber at z = 0.576 in the spectrum of the QSO J0111-0316 in the Cosmic Ultraviolet Baryon Survey. Sp…
The QuaStar Survey: Detecting Hidden Low-Velocity Gas in the Milky Way's Circumgalactic Medium
Hannah V. Bish, Jessica K. Werk, Joshua Peek +2
From our position embedded within the Milky Way's interstellar medium (ISM), we have limited ability to detect gas at low relative velocities in the extended Galactic halo because…

Nicolas Garavito-Camargo, Gurtina Besla, Chervin F. P. Laporte +5
Indications of disequilibrium throughout the Milky Way (MW) highlight the need for compact,flexible, non-parametric descriptions of phase--space distributions of galaxies. We prese…
