ResumoObserved: X-ray and radio emission generally indicate early evolutionary stages and intrinsic redshift. Plasmoids ejected from an active nucleus can fragment or ablate during passage through galactic and intergalactic medium which results in the forming of groups and clusters of proto galaxies. The most difficult result for astronomers to accept is galaxy clusters which have intrinsic redshifts. Yet the association of clusters with lower redshift parents is demonstrated in Arp and Russell, 2001 [1]. Individual cases of strong X-ray clusters are exemplified by elongations and connections as shown in the ejecting galaxy Arp 220, in Abell 3667 and from NGC 720 (again, summarized in Arp, 2003 [4]). Motion is confirmed by bow shocks and elongation is interpreted as ablation trails. In short — if a quasar evolves into a galaxy, a broken up quasar evolves into a group of galaxies.
