Massive Neutrinos and Galaxy Formation
Abstract
We report the most recent results from high-resolution numerical simulations of structure formation in two flat cold+hot dark matter models with neutrino mass densities =0.2 and 0.3. We find that structure forms too late in all CDM+HDM models with >0.2 to account for the amount of dense neutral gas in high-redshift damped Lyman-α systems. The =0.2 model at z≈0 provides a better match to observations than the pure CDM model.
