Secondary infall and the pseudo-phase-space density profiles of cold dark matter haloes
Secondary infall and the pseudo-phase-space density profiles of cold dark matter haloes
We use N-body simulations to investigate the radial dependence of the density and velocity dispersion in cold dark matter (CDM) halos. In particular, we explore how closely Q rho/sigma^3, a surrogate measure of the phase-space density, follows a power-law in radius. Our study extends earlier work by considering, in addition …
