AuthorsHickson, Paul; Mendes de Oliveira, Claudia; Huchra, John P.; Palumbo, Giorgio G. C.
AbstractWe present radial velocities for 457 galaxies in the 100 Hickson compact groups. More than 84% of the galaxies measured have velocities within 1000 km s^-1^ of the median velocity in the group. Here 92 groups have at least three accordant members, and 69 groups have at least four. The radial velocities of these groups range from 1380 to 41,731 km s^- 1^ with a median of 8889 km s^-1^, corresponding to a median distan ...
