Environmental Dependence of Cold Dark Matter Halo Formation


We use a high-resolution N -body simulation to study how the formation of cold dark matter (CDM) halos is affected by their environments, and how such environmental effects produce the age-dependence of halo clustering observed in recent N -body simulations. We estimate, for each halo selected at redshift z = 0, an ‘initial’ massMi defined to be the mass… (More)
