Numerical simulations of the cosmic star formation history.

ASCASIBAR Y., YEPES G., GOTTLOEBER S. and MUELLER V.

Abstract (from CDS):

The cosmic star formation history in Cold Dark Matter dominated cosmological scenarios is studied by means of hydrodynamical numerical simulations. In particular, we explore a low density model with a Λ-term and two high density models with different power spectra, all of them being spatially flat. Our simulations employ a fully nonlinear N-body and Eulerian hydrodynamics algorithm with a model for star formation and supernovae feedback that depends on two phenomenological parameters determined in agreement with previous papers. We find a nearly constant star formation rate beyond z=1, and we discuss which facts may determine the decrease in the SFR from z=1 to the present epoch. The Λ-term cosmology with realistic parameters for star formation and feedback best reproduces the observed star formation history.
