Simulations of a tuned 1:1 head-on merger reproducing NGC 1052's E4 shape generate tidal dwarf galaxies with sizes matching the observed DM-free dwarfs.
New SBF distance confirms NGC5846_UDG1 lies in the NGC 5846 group and reconciles prior GC counts to ~50 members, supporting a massive dark matter halo.
High-mass quiescent galaxies in clusters assemble more luminous stellar halos than field galaxies while low-mass cluster galaxies assemble less luminous ones over 0.1 < z < 1.
