We investigate stellar metallicity distribution functions (MDFs), including Fe and α-element abundances, in dwarf galaxies from the Feedback in Realistic Environment (FIRE) project. We examine both isolated dwarf galaxies and those that are satellites of a Milky Way-mass galaxy. In particular, we study the effects of including a sub-grid turbulent model for the diffusion of metals in gas. Simulations that include diffusion have narrower MDFs and abundance ratio distributions, because diffusion… Expand

The origin of the diverse morphologies and kinematics of Milky Way-mass galaxies in the FIRE-2 simulations.
Hydrodynamic cosmological zoom-in simulations from the Feedback in Realistic Environments project are used to explore the morphologies and kinematics of 15 Milky Way (MW)-mass galaxies, finding the best predictor of morphology is the spin of the gas in the halo at the time the galaxy formed 1/2 of its stars.
