On the properties of elliptical and spiral galaxies in a CDM scenario

This paper aims to investigate what kind of density perturbations did lead to elliptical galaxies and what kind to spiral galaxies, in the context of a CDM scenario. Previous work by HP (Heavens and Peacock, 1988) is reviewed and extended; more particularly: (i) a theoreticalJ∼M ξ relation is derived for virialized configurations, with a slope increasing with the mass, in the range 5/3
