The asymmetry of the Coma cluster of galaxies

A detailed reinvestigation of the Coma cluster basing on enlarged observational material of number density distributions and radial velocities of galaxies as well as radio and x-ray data is performed and supports our previous conclusion that this cluster possesses a substructure. This substructure is in the south-western region of the cluster and produces the impression of an elongated cluster structure in the direction of the bridge between Coma and A 1367. A 1656 seems to be a cD-like cluster with NGC 4874 as the only dominating giant central galaxy.
