Clusters of galaxies are studied from a theoretical point of view, comparing with observational results whenever possible. The problem is approached both analytically as well as by means of high-resoultion numerical simulations. The dark matter halo, the hot intracluster gas, and the stellar component are investigated separately. Numerical clusters are consistent with a relatively simple scenario, in which these objects form around local maxima of the primordial density field, smoothed on Mpc… Expand
