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…
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 +8
APOGEE and Gaia data have revealed that the Milky Way's structure appears to have evolved through three distinct kinematic phases. First, at early cosmic times, the Milky Way was a…
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…
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…
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…
