Group of galaxies in the constellation of Coma Berenices
NGC 4065 Group
SDSS image of the NGC 4065 Group. The two subclusters surrounding the galaxy pair NGC 4061 and NGC 4065 (lower right) and NGC 4095 (upper left) can be seen.
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 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.
