The origin of strong -element bimodalities in FIRE simulations of Milky Way-mass galaxies
Megan Barry, Andrew Wetzel, Sarah Loebman +2
One of the Milky Way's characteristic features is a strongly bimodal distribution of -process elements, such as Mg, at fixed [Fe/H] in stellar abundances. We examine patterns i…

Effect of gas accretion on -element bimodality in Milky Way-mass galaxies in the FIRE-2 simulations
Hanna Parul, Jeremy Bailin, Sarah R. Loebman +3
We analyse the stellar distributions on the [Fe/H]-[Mg/Fe] plane for 11 Milky Way-mass galaxies from the FIRE-2 cosmological baryonic zoom-in simulations. Alpha-element bimodality,…

LMC-driven anisotropic boosts in stream--subhalo interactions
Arpit Arora, Nicolás Garavito-Camargo, Robyn E. Sanderson +4
Dark Matter (DM) subhalos are predicted to perturb stellar streams; stream morphologies and dynamics can constrain the mass distribution of subhalos. Using FIRE-2 simulations of Mi…
