Apparent associations between bright galaxies and quasi-stellar objects.
Abstract
A comparison of the spatial distribution of the 47 identified QSOs in the 3C and 3CR catalogs with the small-redshift galaxies contained in the Reference Catalog of Bright Galaxies shows that four QSOs with redshift in the range 0.5-1.4 are much closer to bright galaxies than would be expected if the 47 QSOs were distributed randomly. An extensive analysis of the distributions shows that the probability that this is a chance occurrence is less than 0.005. It is also shows that the radio-quiet QSO PHL 1226 lies very close to IC 1746 to which it appears to have a physical connection.
