Abstract
The distribution on the sky of clusters of galaxies shows significant assoc iation with relatively nearby, large, active galaxies. The pattern is that of clusters paired equidistant across a central galaxy with the apparent ma gnitudes and redshifts of their constituent galaxies being closely matched. The clusters and the galaxies in them tend to be strong X-ray and radio em itters, and their redshifts occur at preferred redshift values. The central , low-redshift galaxies often show evidence of ejection in the direction of these higher redshift clusters. In all these respects the clusters resembl e closely quasars which have been increasingly shown for the last 34 years to be similarly associated with active parent galaxies. New, especially sig nificant pairings of quasars are presented here, which are, at the same tim e, associated with Abell clusters of galaxies. It is argued here that, empi rically, the quasars are ejected from active galaxies. They evolve to lower redshift with time, forming stars, and fragmenting at the end of their dev elopment into clusters of low-luminosity galaxies. The cluster galaxies can be at the same distance as their lower redshift parents because they still retain a component of their earlier, quasar intrinsic redshift.
