OBSERVATION OF X-RAY DARK CD CLUSTER A2162
ABSTRACT
A2162 has exceptionally small X-ray luminosity comparing with its large cD envelope. We suggest this object is in a transition phase from isolated cD galaxy to cluster of galaxies. If the gravitational potential of cluster is getting virialized at the present, the gas temperature and the dark matter density should be significantly smaller than average rich clusters. This object give us an excellent opportunity to test hierarchical clustering theory.
