چکیده انگلیسی
Abell 85 is a cD cluster of galaxies with the redshift of 0.055 in the southern hemisphere. Based on the spectroscopic data obtained by predecessors and the data of the SDSS (Sloan Digital Sky Survey), 370 member galaxies of the cluster are sieved by means of the 3σ method and their dynamical states are analyzed. From the spatial distribution and the local line-of-sight velocity distribution of these member galaxies it is found that this cluster of galaxies contains 4 clear substructures and they are just in the process of pairwise coalescence. This shows that the cluster Abell 85 is in the actively dynamical state, far from reaching the dynamical equilibrium.
