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…

Gas Kinematics in FIRE Simulated Galaxies Compared to Spatially Unresolved HI Observations

Kareem El-Badry, Jeremy Bradford, Eliot Quataert +9

The shape of a galaxy's spatially unresolved, globally integrated 21-cm emission line depends on its internal gas kinematics: galaxies with rotation-supported gas disks produce dou…
