The TRGB distance to the second galaxy "missing dark matter": evidence for two groups of galaxies at 13.5 and 19 Mpc in the line of sight of NGC 1052.

MONELLI M. and TRUJILLO I.

Abstract (from CDS):

A second galaxy "missing dark matter" (NGC 1052-DF4) has been reported recently. Here we show, using the location of the tip of the red giant branch (TRGB), that the distance to this galaxy is 14.2 ± 0.7 Mpc. This locates the galaxy 6 Mpc closer than previously determined. We also analyze the distances to the brightest galaxies in the field of view of NGC 1052. We find that this field is populated by two groups of galaxies in projection: one dominated by NGC 1052 and NGC 1047 at ∼19 Mpc, and another group containing NGC 1042 and NGC 1035 (as well as [KKS2000]04 and NGC 1052-DF4) at ∼13.5 Mpc. At a distance of 13.5 Mpc the globular clusters of NGC 1052-DF4 have the same properties as globular clusters in the Milky Way and other dwarf galaxies.
