2002ApJ...565..849C The Nearest Neighbor Alignment of Cluster X-Ray Isophotes Scott W. Chambers, Adrian L. Melott, and Christopher J. Miller Received 2001 February 7; accepted 2001 September 10 ABSTRACT We examine the orientations of rich galaxy cluster X-ray isophotes with respect to their rich nearest neighbors using existing samples of Abell cluster position angles measured from Einstein and ROSAT observations. We study a merged subset of these samples using updated and improved positions and redshifts for Abell/ACO clusters. We find high confidence for alignment, which increases as nearest neighbor distance is restricted. We conclude that there is a strong alignment signal in all this data, consistent with gravitational instability acting on Gaussian perturbation.
