Stars made in outflows may populate the stellar halo of the Milky Way
Sijie Yu, James S. Bullock, Andrew Wetzel +8
We study stellar-halo formation using six Milky Way-mass galaxies in FIRE-2 cosmological zoom simulations. We find that of the outer ( kpc) stellar halo in each sy…
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…
Is it possible to reconcile extragalactic IMF variations with a universal Milky Way IMF?
David Guszejnov, Philip F. Hopkins, Andrew S. Graus
One of the most robust observations of the stellar initial mass function (IMF) is its near-universality in the Milky Way and neighboring galaxies. But recent observations of early-…
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…
