Galaxy associations within the Coma cluster.

GURZADYAN V.G. and MAZURE A.

Abstract (from CDS):

The mean redshift of the core of the Coma cluster – cz=6953 km s-1 and its dispersion σ=949 km s-1 are obtained by means of the analysis of the substructures of this cluster by using the S-tree method. The existence of three subgroups of galaxies is revealed, one of them is associated with the cD galaxy NGC 4874, the other – with NGC 4889. It is argued that these subgroups are galaxy associations, i.e. galactic dynamical entities moving within the main cluster. Thus, we conclude that the non-stationarity of the dynamical processes ongoing in the Coma core is due to the merging of small-scale galaxy associations, rather than of two equal sized clusters. We provide the lists of the galaxies of the associations, the observational study of which can be of particular interest.
