The Cluster of Galaxies Abell 1413
Abstract
The cluster Abell 1413 at a redshift of 0.143 shows an effect which may be interpreted as a luminosity segregation, indicating that this property probably persists over look-back times of order 0.14 of the inverse of the Hubble constant. The cluster has the same richness as the Coma cluster but only about 60% as the radius, unless what appears to be the brightest member is really a foreground galaxy.
