The Adapted Morphological Types of 247 Rich PF Galaxy Clusters

TL;DR

This study classifies 247 rich galaxy clusters using adapted morphological criteria, revealing that concentration and preferential plane are significant, independent features for understanding cluster structure.

Contribution

Introduces an adapted morphological classification scheme for galaxy clusters that incorporates concentration, preferential direction, and brightest galaxy positions.

Findings

Both concentration and preferential plane are significant criteria.

The criteria are independent and provide new insights into cluster morphology.

The classification enhances understanding of galaxy cluster structures.

Abstract

Morphological types were determined for 247 rich galaxy clusters from the PF Catalogue of Galaxy Clusters and Groups. The adapted types are based on classical morphological schemes and consider concentration to the cluster center, the signs of preferential direction or plane in the cluster, and the positions of the brightest galaxies. It is shown that both concentration and preferential plane are significant and independent morphological criteria.
