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.

Image stacking of 57 E+A galaxies shows excess extended light relative to comparison samples, consistent with faint tidal features from small-scale interactions.
Multi-band imaging and Keck spectroscopy identify a z=0.92 galaxy pair as a physical merger at ~5 kpc projected separation with merger-induced star formation.
