Abstract

The results of analyses for 43 clusters and groups of galaxies (z = 0.004-0.37) observed with ASCA are presented. These data was systematically analyzed with same way to reveal common properties and obtained following physical parameters; X-ray luminosity (10^40-46 h₅₀^-2 ergs s^-1), flux-weighted temperature (0.7-12 keV), iron abundance (0.07-0.6 cosmic), X-ray morphological parameters like core radius, 300 kpc) and beta (0.3-0.9), the gas mass, total iron mass and gravitational mass. Results were also compared with the optical properties taken from the literature, velocity dispersion, galaxy number density, galaxy mass, and optical morphological parameters. Based on these results, we investiga te the origin of heavy elements, distribution of dark matter and evolution of clusters of galaxies.
