In TNG-50, 80% of Milky Way-mass galaxies align their present-day angular momentum with the orbital angular momentum of their most massive merger, and 81% of their stellar halos rotate prograde relative to the disk.

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.
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.
