摘要：

Recently there has been a lot of attention focused on a virialized halo-based approach to understanding the properties of the matter and galaxy power spectrum. A key ingredient in this model is the number and distribution of galaxies within dark matter halos as a function of mass. This quantity has been predicted from semianalytic modeling and from fits to observational data. Here we present predictions for the occupation number and spatial distribution of subhalos based on a high-resolution hydrodynamical simulation including cooling, star formation, and feedback.
