Morphological classification and structural parameters of galaxies in the Coma and Perseus clusters

Year: 1997

Type: article

Abstract: We present the results of an isophotal shape analysis of galaxies in the Coma and Perseus clusters. These data, together with those of two previous papers, provide two complete samples of galaxies with reliable Hubble types in rich clusters: 1) all galaxies brighter than falling within one degree ( Mpc) from the center of the Coma cluster (187 galaxies), 2) all galaxies brighter than in a region of 5°3' × 5°27' around the center of the Perseus cluster (139 galaxies). These two complete samples cover 5 orders of magnitude in galaxy density and span areas of 91 and 17 Mpc2, clustercentric radii up to 6.4 and 2.3 Mpc, for Perseus and Coma respectively. They will be used in subsequent papers to study the dependence of galaxy types on cluster environment and as reference samples in comparisons with distant clusters.
