The NGC 4065 Group is a group of galaxies[1][2][3][15] located about 330 Mly (100 Mpc)[1][3] in the constellation Coma Berenices.[10][16] The group's brightest member is NGC 4065[4][15][17][18] and located in the Coma Supercluster.[3][7][15][19][20][21][22][23]
The group is dominated by mostly elliptical galaxies[10][19] with only 15 to 31 percent of the members being spiral galaxies.[4][15]
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.[4]
Structure
The NGC 4065 Group appears to consist of two subgroups known as UZC-CG 156 and UZC-CG 157[3][4] which are indistinguishable by velocity.[3]
However, White et al. suggests that the group contains three subgroups[8] with subgroups A and C[8] being centered on NGC 4065 and NGC 4095 respectively,[10] and subgroup B which consists of the galaxies NGC 4086 and NGC 4090.[8]
At the center of the group lie the elliptical galaxies NGC 4061 and NGC 4065.[4]
Nearby groups
The NGC 4065 Group is located near the Leo Cluster[3][15] and is part of a bridge of galaxies that connects the Leo Cluster to the Coma Cluster.[15][17][24]
