A Relationship Between Stellar Metallicity Gradients and Galaxy Age in Dwarf Galaxies
Francisco J. Mercado, James S. Bullock, Michael Boylan-Kolchin +7
We explore the origin of stellar metallicity gradients in simulated and observed dwarf galaxies. We use FIRE-2 cosmological baryonic zoom-in simulations of 26 isolated galaxies as…
A dark matter profile to model diverse feedback-induced core sizes of CDM haloes
Alexandres Lazar, James S. Bullock, Michael Boylan-Kolchin +11
We analyze the cold dark matter density profiles of 54 galaxy halos simulated with FIRE-2 galaxy formation physics, each resolved within of the halo virial radius. These ha…
Star formation histories of dwarf galaxies in the FIRE simulations: dependence on mass and Local Group environment
Shea Garrison-Kimmel, Andrew Wetzel, Phillip F. Hopkins +13
We study star formation histories (SFHs) of dwarf galaxies (stellar mass ) from FIRE-2 cosmological zoom-in simulations. We compare dwarf…
A Predicted Correlation Between Age Gradient and Star Formation History in FIRE Dwarf Galaxies
Andrew S. Graus, James S. Bullock, Alex Fitts +9
We explore the radial variation of star formation histories in dwarf galaxies simulated with Feedback In Realistic Environments (FIRE) physics. The sample contains 9 low-mass field…
Dwarf Galaxies in CDM, WDM, and SIDM: Disentangling Baryons and Dark Matter Physics
Alex Fitts, Michael Boylan-Kolchin, Brandon Bozek +9
We present a suite of FIRE-2 cosmological zoom-in simulations of isolated field dwarf galaxies, all with masses of M at , across a r…
Warm FIRE: Simulating Galaxy Formation with Resonant Sterile Neutrino Dark Matter
Brandon Bozek, Alex Fitts, Michael Boylan-Kolchin +8
We study the impact of a warm dark matter (WDM) cosmology on dwarf galaxy formation through a suite of cosmological hydrodynamical zoom-in simulations of $M_{\rm halo} \approx10^{1…
