Resolving galaxy formation in the early Universe with BonFIRE and CampFIRE
Jenna Samuel, Michael Boylan-Kolchin, Robert Feldmann +16
The abundance and rapid growth of galaxies at cosmic dawn revealed by the James Webb Space Telescope challenges models of galaxy formation, motivating new simulations to uncover th…
From protogalaxy through thick and thin: Why did the Milky Way evolve in three kinematic phases?
Olti Myrtaj, James S. Bullock, Michael Boylan-Kolchin +9
APOGEE and Gaia data suggest the Milky Way's kinematic structure evolved through three distinct phases: a disordered protogalaxy, which ``spun up'' into a thick stellar disk, and t…
Cold vs. Hot Gas Accretion and Angular Momentum in FIRE Simulations: From Halo to Galaxy Scales
Imran Sultan, Claude-André Faucher-Giguère, Jonathan Stern +1
We present a systematic study of gas accretion and angular momentum in the circumgalactic medium (CGM) using high-resolution FIRE cosmological simulations. Our analysis includes ha…
Enhanced Multiphase Circumgalactic Medium and Gas Cycling in Galaxy Mergers
Maolan Yang, Suoqing Ji, Robert Feldmann +9
We investigate the impact of galaxy mergers on the circumgalactic medium (CGM) using the FIREbox cosmological hydrodynamic simulation. By comparing matched samples of merging and i…
Accretion-Driven Turbulence in the Circumgalactic Medium
Roy Goldner, Jonathan Stern, Drummond Fielding +3
Simulations suggest that turbulence is ubiquitous in the circumgalactic medium (CGM), though the source and properties of CGM turbulence is uncertain. Using analytic considerations…
Project AMIGA: The Inner Circumgalactic Medium of Andromeda from Thick Disk to Halo
Nicolas Lehner, J. Christopher Howk, Lucy Collins +22
The inner circumgalactic medium (CGM) of galaxies, where disk and halo processes intersect, remains poorly characterized despite its critical role in regulating galaxy evolution. W…
Turbulence-dominated CGM: the origin of UV absorbers with equivalent widths of Å
Aharon Kakoly, Jonathan Stern, Claude-André Faucher-Giguère +4
Theoretical arguments and observations suggest that in massive halos (), the circumgalactic medium (CGM) is dominated by a 'hot' phase with gas temperature near…
The Shape of FIREbox Galaxies and a Potential Tension with Low-mass Disks
Courtney Klein, Jenny D. Wang, Luke Xia +9
We study the intrinsic and observable shapes of approximately 700 star-forming galaxies with stellar masses of M from the FIREbox simulation at . We c…
Cooling Flows as a Reference Solution for the Hot Circumgalactic Medium
Imran Sultan, Claude-André Faucher-Giguère, Jonathan Stern +3
The circumgalactic medium (CGM) in halos is dominated by a hot phase ( K). While many models exist for the hot gas structur…
Comparison of Models for the Warm-Hot Circumgalactic Medium around Milky Way-like Galaxies
Priyanka Singh, Erwin T. Lau, Yakov Faerman +2
A systematic comparison of the models of the circumgalactic medium (CGM) and their observables is crucial to understanding the predictive power of the models and constraining physi…
X-ray signatures of galactic outflows into the circumgalactic medium
Ranita Jana, Kartick C. Sarkar, Jonathan Stern +1
We present a set of controlled hydrodynamical simulations to study the effects of strong galactic outflows on the density and temperature structures, and associated X-ray signature…
Ne VIII in the warm-hot circumgalactic medium of FIRE simulations and in observations
Nastasha A. Wijers, Claude-André Faucher-Giguère, Jonathan Stern +2
The properties of warm-hot gas around galaxies can be studied with absorption lines from highly ionized metals. We predict Ne VIII column densities from cosmological z…
CGM properties in VELA and NIHAO simulations; the OVI ionization mechanism: dependence on redshift, halo mass and radius
S. Roca-Fàbrega, A. Dekel, Y. Faerman +8
We study the components of cool and warm/hot gas in the circumgalactic medium (CGM) of simulated galaxies and address the relative production of OVI by photoionization versus colli…
