Cosmic cannibals
Abstract
The collision and subsequent assimilation of small galaxies by larger ones are examined in connection with cD galaxy radio sources. The dynamic-friction galactic-cannibalism theory is reviewed. It is noted that galactic cannibalism accounts for the relative absence of bright galaxies other than cD galaxies in rich clusters.
