Fine Structure Within the Redshift-Magnitude Correlation for Galaxies : Proceedings of the 58th IAU Symposium (1973)

Abstract

Previous work on the redshift- magnitude banding correlation is briefly reviewed. New tests of the concept are applied successfully to a second cluster (A2199) and the outer portions of the Coma cluster. Using more than 200 redshifts in Coma, Perseus, and A2199 the presence of a distinct band - related- periodicity in redshift is indicated. Finally, a new sample of accurate redshifts of bright Coma galaxies on a single band is presented, which shows a strong redshift periodicity of 220 km sec -1. An upper limit of 20 km sec -1 is placed on the internal Doppler component of motion in the Coma cluster. Redshift- magnitude bands are, therefore, now recognized to consist of discrete "spin states" organized into "spin groups" which show strong mor- phological associations. Bands are probably in turn organized into band systems. The individual spin states are suggested to represent distinct configurations of matter at the nuclear or fundamental particle structure level. Transitions between states in a time systematic sense of decreasing redshift (increasing internal binding) is suggested to occur in galaxy nuclei. Energy released in such transitions is suggested as the driving energy in radio sources and related objects.
