On the distribution of galaxy ellipticity in clusters
We study the distribution of projected ellipticity n(ε) for galaxies in a sample of 20 rich (Richness ≥ 2) nearby (z < 0.1) clusters of galaxies. We find no evidence of differences in n(ε), although the nearest cluster in the sample (the Coma Cluster) is the largest outlier (P(same) < 0.05). We then study n(ε) within the clusters, and find that ε increases with projected cluster-centric radius R (hereafter the ε-R relation). This trend is preserved at fixed magnitude, showing that this relation...[Show more]
