Pickles on FIRE: The 3D Shape Evolution of Simulated Milky Way-Mass Galaxies
Luke Y. Xia, Courtney Klein, Jenny D. Wang +6
We use reduced-mass eigentensors to quantify the 3D ellipsoidal shape evolution of thirteen Milky Way-mass galaxies simulated using zoom simulations with FIRE-2 physics; all but on…
Hot accretion onto spiral galaxies: the origin of extended and warped HI discs
Sriram Sankar, Jonathan Stern, Chris Power +6
Gas accretion, hot ( K) atmospheres, and a tilt between the rotation axes of the disc and the atmosphere are all common predictions of standard galaxy evolution theory f…
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…
Bloodhound Unleashed: Particle-based Substructure Tracking for Cosmological Simulations
Hyunsu Kong, Michael Boylan-Kolchin, James S. Bullock
Modern studies of galaxy formation rely heavily on numerical simulations, which in turn require tools to identify and track self-bound structures in stars and dark matter. In this…
Rise of the forsaken relics: connecting present-day stellar streams and phase-mixed galaxies to the Epoch of Reionization
Aritra Kundu, Robyn Sanderson, Adam Lidz +6
The `near-far' approach to studying reionization leverages the star formation histories of the Milky Way (MW) or Local Group (LG) galaxies, derived from resolved photometry, to inf…
