The Gaia-Sausage-Enceladus merger occurred 11.2 ± 0.1 Gyr ago, coinciding with the formation of a group of globular clusters and potentially leaving ω Centauri as its remnant, while placing disk formation at z ≳ 4.
Abundances and Ba isotopic ratios in TYC 6044-714-1 are best reproduced by s+r nucleosynthesis models; i+s+r models require extreme conditions and fail to match the full pattern.
The PFS Galactic Archaeology survey will observe thousands of stars in Local Group systems to measure density profiles in dwarfs and compare assembly histories of M31 and the Milky Way.
