High-redshift galaxies in cold dark matter models

Abstract

We use hydrodynamic cosmological simulations to predict the star formation properties of high-redshift galaxies (z = 2 − 6) in five variants of the inflationary cold dark matter scenario, paying particular attention to z = 3, the redshift of the largest “Lyman-break galaxy” (LBG) samples. Because we link the star formation timescale to the local gas density… (More)
