Simulations of a tuned 1:1 merger of NGC 1052 produce long-lived tidal tails and dwarf galaxies matching observed sizes of DM-free dwarfs, unlike the dwarf bullet model.
Five of seven modeled M31 dwarf spheroidals show anomalously low central DM densities at 150 pc, with star formation heating disfavored as the sole cause.
Derivative test on SPARC galaxies shows outer rotation curves are consistent with flat profiles rather than Keplerian taper.
