Ukrainian Journal of Physics| Summary: | This work has analyzed the observational data on galaxy clusters from SDSS DR8. Based on the observational data on the distribution of a surface density, the values of the anisotropy parameter are determined for 31 clusters. A classification of galaxy clusters based on the velocity anisotropy parameters is proposed, according to which the clusters are divided into three groups. The relationship between the anisotropy parameter and the main physical characteristics of galaxy clusters has been studied. |
