Additional members of the local group of galaxies and quantized redshifts within the two nearest groups.
Abstract
Published observational data on galaxies of redshift z less than about 1000 km/s are compiled in extensive tables and diagrams and analyzed, searching for additional Local Group members among fainter higher-redshift galaxies. A concentration toward the center of the Local Group and a concentration associated with NGC 55, NGC 300, and NGC 253 are identified in the south Galactic hemisphere and characterized in detail. The galaxies near the centers of the concentrations are found to obey a quantization interval of Delta-cz0 = 72.4 km/s, as for the Local Group (Tifft, 1977); the accuracy of this finding is shown to be to within + or - 8.2 km/s (for galaxies with redshifts known to + or - 8 km/s) and to within 3-4 km/s (for a subset of galaxies with more accurately measured redshifts).
