摘要

We show that in a hierarchical clustering model the low-order statistics of the density and the peculiar velocity fields can all be modelled semi-analytically for a given cosmology and an initial density perturbation power spectrum P(k). We present such models for the two-point correlation function ξ(r), the amplitude Q of the three-point...更多
