Clusters Of Galaxies: Densities

Scientific paper

The authors perform a statistical analysis of the galaxy density profiles of clusters of galaxies. They consider all clusters of galaxies with published redshifts z < 0.12 in the area covered by the COSMOS/UKST Southern Sky Galaxy Catalogue. The results of the statistical analysis indicate that a single power-law model provides a very good fit to the data. Cluster density profiles are found consistent with an isothermal model with a weak tendency toward flatter profiles for richer objects.
