The Alignment of rich ACO galaxy structures
Abstract
We analysed the existence of the Binggeli effect in 377 rich ACO tep{Abell} galaxy clusters taken from Digital Sky Survey I with known morphological types and redshift z<0.2. We searched for an excess of small values of the acute angle Δθ, measured as the difference between the direction toward neighbouring clusters and the direction of the cluster position angle. The strongest effect was found for Bautz-Morgan tep[][hereafter BM]{Bautz} type I clusters with ellipticities e>0.2.
