Milky Way abundance trends act as effective empirical proxies for nucleosynthetic yields, recovering alpha and Fe-peak abundances in quiescent galaxies with 0.05 dex median offset versus 0.23 dex for theory, indicating largely universal yields.

The Milky Way stellar halo is radially anisotropic inside ~35 kpc and becomes tangentially dominated farther out; after removing known accreted structures the profile stays radially biased at all radii.
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.
Simulations show that observed rotation in 13.5-Gyr-old alpha-rich stars constrains the Gaia-Sausage-Enceladus merger to mass ratios below 1:4, with interaction and starburst times both near 11 Gyr.
Sextans dSph is a composite system from a minor merger 13 Gyr ago, with metal-poor core and more evolved accreted envelope showing inverse metallicity gradient.
In the Magneticum simulation, a more circular satellite orbit produces a stream where visible stars come mostly from the progenitor core while a radial orbit produces shells that preserve the original radial ordering of stars from the satellite.

Stream on: Evolution of stellar shells and streams - A case study
In the Magneticum simulation, a more circular satellite orbit produces a stream where visible stars come mostly from the progenitor core while a radial orbit produces shells that preserve the original radial ordering of stars from the satellite.
