The origin of metal-poor stars on prograde disk orbits in FIRE simulations of Milky Way-mass galaxies
Isaiah B. Santistevan, Andrew Wetzel, Robyn E. Sanderson +3
In hierarchical structure formation, metal-poor stars in and around the Milky Way (MW) originate primarily from mergers of lower-mass galaxies. A common expectation is therefore th…

The Formation Times and Building Blocks of Milky Way-mass Galaxies in the FIRE Simulations
Isaiah B. Santistevan, Andrew Wetzel, Kareem El-Badry +5
Surveys of the Milky Way (MW) and M31 enable detailed studies of stellar populations across ages and metallicities, with the goal of reconstructing formation histories across cosmi…
