Star formation history since z=1.5 as inferred from rest-frame ultraviolet luminosity density evolution.

Abstract (from CDS):

We investigate the evolution of the universal rest-frame ultraviolet luminosity density from z=1.5 to the present. We analyze an extensive sample of multicolor data (U'AB, BAB, VAB=24.5) plus spectroscopic redshifts from the Hawaii Survey Fields and the Hubble Deep Field. Our multicolor data allow us to select our sample in the rest-frame ultraviolet (2500 Å) over the entire redshift range to z=1.5. We conclude that the evolution in the luminosity density is a function of the form (1+z)1.7±1.0 for a flat lambda (Ωm0=0.3, Ωλ0=0.7) cosmology and (1+z)2.4±1.0 for an Einstein-de Sitter cosmology.
