1998Afz....41...32P One Arc Degree Core Substructure of the Virgo Cluster Petrosian, A. R.; Gurzadyan, V. G.; Hendry, M. A.; Nikoghossian, E. H. Abstract. The results of analysis of the substructure of 1 degree field galaxies of the Virgo cluster by means of the Stree technique developed by Gurzadyan et al. are presented. The existence of 3 main subgroups is shown and their dynamical parameters are obtained. The mass centers of the subgroups appear to be aligned in the direction parallel to the elongation of the Virgo cluster. The morphological analysis shows some domination of dwarf galaxies in the subgroup A containing M 87, and existence of two spiral galaxies N4425 and N4461; the latter fact can be crucial for the estimation of the distance of the Virgo cluster by means of the search for Cepheids in the spirals.
