NGC 4065 Group explained

The NGC 4065 Group is a group of galaxies[1] [2] [3] located about 100Mpc[4] in the constellation Coma Berenices.[5] [6] The group's brightest member is NGC 4065[3] [7] [8] and located in the Coma Supercluster.[9] [3] [10] [11] [12] [13] [14]

The group is dominated by mostly elliptical galaxies with only 15 to 31 percent of the members being spiral galaxies.[3]

X-ray emission

The NGC 4065 Group exhibits bimodal X-ray emission with one peak on the galaxies NGC 4061 and NGC 4065 and the other on NGC 4066.

Structure

The NGC 4065 Group appears to consist of two subgroups known as UZC-CG 156 and UZC-CG 157 which are indistinguishable by velocity. However, White et al. suggests that the group contains three subgroups[15] with subgroups A and C being centered on NGC 4065 and NGC 4095 respectively, and subgroup B which consists of the galaxies NGC 4086 and NGC 4090.

At the center of the group lie the elliptical galaxies NGC 4061 and NGC 4065.

Nearby groups

The NGC 4065 Group is located near the Leo Cluster[3] and is part of a bridge of galaxies that connects the Leo Cluster to the Coma Cluster.[3] [16]
