The Structure of Cold Dark Matter Halos: Recent Insights from High Resolution Simulations

Abstract

We review results from recent high resolution cosmological structure formation simulations, namely the Via Lactea I & II and GHALO projects. These simulations study the formation of Milky Way sized objects within a cosmological framework. We discuss the general properties of cold dark matter halos at redshift z = 0 and focus on new insights into the structure of halos we got due to the unprecedented high resolution in these simulations.Comment: 16 pages, 5 figures, invited brief review for MPL
