Session 29 - Dynamical Evolution of Galaxies.

The MKW and AWM poor clusters are very different environments from rich Abell clusters. We obtained images with the Jacobus Kapteyn Telescope of 21 brightest cluster members (BCM) of the MKW/AWM clusters and determined that the major axis of the BCMs exhibits alignments similar to those in rich cluster dominant galaxies. Specifically, the major axes of the poor cluster BCMs point to nearby (< 20 Mpc) Abell clusters. Using the Kolmolgorov-Smirnov test, we reject the hypothesis that the position angles are randomly distributed at the 97responsible for dominant galaxy alignments are therefore independent of cluster richness.
