12 Oct 1999 | | Subject: | astro-ph | | Affiliation: | Princeton), Lars Hernquist (CfA), Neal Katz (UMass), David H. Weinberg (Ohio State | | Abstract: | We determine the evolution from $z=3 o 0$ of the galaxy and mass correlation functions and bias factor in a $50h^{-1}$Mpc $Lambda$CDM hydrodynamic simulation with $10h^{-1}$kpc resolution. The mass correlation function grows with time, but the galaxy correlation function shows little evolution and is well described by a power law. At early times, galaxies are biased traces of mass, with bias being higher on smaller scales. By z=0, galaxies trace the mass, and the bias shows little scale dependence. | | Source: | arXiv, astro-ph/9910221 | | Services: | Forum | Review | PDF | Favorites | |
