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 $Λ$ 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 $0.5%$ of the halo virial radius. These ha…
