Abstract

The association of low redshift, active galaxies with high redshift quasars is here tested in two regions uniformly surveyed for quasars to faint limits. Three active galaxies in these regions all show significant association with nearby quasars. Radio, optical and X-ray data available for these galaxies give new information on the processes which accompany the proposed ejection of the quasars. It is concluded that the quasars are originally relatively compact compared to the galactic medium through which they exit but can be slowed. It is argued that effects of ejection can be seen on the galaxies and may be connected with spiral structure. Evidence for periodicity of the redshifts is discussed.
