Galaxy Mergers in a CDM Model
Abstract
A particle code is used to follow the evolution of a Cold Dark Matter spectrum in an Ω = 1 background, treating half of the 524288 particles as a gas that can cool and turn into stars. The number density of galaxies as a function of redshift is well fit by the BBKS peaks statistics, using a sharp threshold having a normalized overdensity νt = 1.44(l + z)/σ0(M), where σ0(M) is the linear extrapolation of the initial RMS density fluctuation on …
