That’s So Retro: The Gaia-Sausage-Enceladus Merger Trajectory as the Origin of the Chemical Abundance Bimodality in the Milky Way Disk

Abstract The Milky Way (MW) is thought to have experienced a ∼3:1 mass-ratio merger event near redshift z ∼ 2 with a significantly retrograde trajectory. This now-disrupted dwarf galaxy is commonly known as the Gaia-Sausage-Enceladus (GSE). In this paper, we investigate the impac...
