Study of Clusters of Galaxies by Correlation Analysis
Abstract
We present preliminary results of the application to real data of a new method for studying the structure of groups and clusters of galaxies. The new method is able to produce reliable results for structures with a small number of galaxies. The 6 clusters whose number density and velocity dispersion profiles are determined, could have hardly been studied with classical methods. These new results are particularly significant, especially in what concerns the velocity dispersion profile, since little is known so far on its characteristics.
