摘要:
The hierarchical nature of halo formation in the Cold Dark Matter (CDM) model suggests that there should be mass dependent trends in the radial velocity and velocity anisotropy profiles of dark matter haloes, with more massive systems exhibiting the effects of more pronounced infall. We present results from a sample of high resolution cosmological N-body simulations of individual dwarf, galaxy and cluster mass haloes, and demonstrate that such trends with mass are indeed observed.
