Abstract
ABSTRACT We investigated the influence of environment on cluster morphology by examining the alignment of the cluster position angle with respect to the nearest neighbour cluster. The cluster position angle and ellipticity were measured using high spatial resolution X-ray data taken from the Chandra archive, while the nearest neighbour sample was extracted from the Abell cluster catalogue. We found high confidence for an alignment when neighbour distance (Dn) was less than 70 h-1 Mpc, while we found no significant variations of the confidence level at various values of Dn less than 70 h -1 Mpc.
