Abstract

Redshifts for nine galaxies in the field of the cluster Abell 2255 are reported and discussed together with six other redshifts of galaxies reported in the literature. The distribution of redshifts indicates that two superposed clusters may have been observed. If this is so, the data presented here and Ariel X-ray data tend to invalidate claims of correlation between velocity dispersion and X-ray luminosity. Dynamics of the cluster combined with radio data allows inferences to be made concerning particle lifetimes. Under either the one-cluster or two-cluster hypothesis, the data indicate that in situ particle acceleration occurs in the radio components after they exit from the parent galaxy.
