Simulations of Milky Way-mass galaxies reveal direction-dependent dynamical heating during stellar radial migration, with inward migrators heating, some cooling, and cold preservation uncommon especially for older stars.

Reprojects abundances of 199k stars into 4 patterns, identifying enrichment pathways with strong chemo-spatial, age, and vertical correlations plus a transition at ~6 Gyr.
Simulations of dwarf galaxies show V/σ rising with stellar mass, with HI gas and young stars more rotation-supported than old stars.
Simulations show Lindblad-resonance wrinkles from non-winding spirals are filled with zero-age stars on orbits normally occupied by much older populations, offering an age-based constraint on past transient spiral patterns.
FIRE-2 simulations show that stellar radial redistribution scatter saturates at ~2 kpc for stars older than ~3 Gyr, with net orbital changes depending on age and current radius, broadly matching Milky Way observations.
