DETECTION OF NONRANDOM GALAXY ORIENTATIONS IN X-RAY SUBCLUSTERS OF THE COMA CLUSTER

摘要

This study on the Coma Cluster suggests that there are deviations from a completely random galaxy orientation on small scales. Since we found a significant coincidence of hot-gas features identified in the latest X-ray observations of Coma with these local anisotropies, they may indicate regions of recent mutual interaction of member galaxies within subclusters that are currently falling in on the main cluster.
