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…
