6 Jul 2004 | | Subject: | astro-ph | | Affiliation: | Depto. de Astronomia, Univ. Guanajuato, Mexico, Tartu Obs. Toravere, Estonia, Inst. of Physics, Tartu, Estonia | | Abstract: | The June 2004 version of our compilation of measured redshifts for clusters in the Abell-ACO catalogue lists redshifts for 3715 clusters/subclusters in 3033 distinct (2396 A- and 637 S-) clusters, 67% of these with N_z>=3 galaxies measured. We provide velocity dispersions (sigma_V) for 1875 (sub)clusters towards 1353 unique ACO clusters. The median sigma_V is 650 km/s for A-(sub)clusters and 575 km/s for S-(sub)clusters, and sigma_V clearly increases with both, N_z and richness, and also, somewhat surprising, with later Bautz-Morgan type of the clusters. We show examples of supercluster properties based on these data. | | Source: | arXiv, astro-ph/0407097 | | Services: | Forum | Review | PDF | Favorites | |
