The ultraviolet extragalactic background light: dust extinction and the evolution of the cosmic star formation rate from z = 0 to ∼0.6

We show that the accumulated light of galaxies in the ultraviolet can be evaluated from their luminosity density as a function of the evolution of the cosmic star formation rate and dust extinction properties. Constraints on the evolution rate are expected in future. Data available at the moment are...

Summary:We show that the accumulated light of galaxies in the ultraviolet can be evaluated from their luminosity density as a function of the evolution of the cosmic star formation rate and dust extinction properties. Constraints on the evolution rate are expected in future. Data available at the moment are consistent with an evolution rate at low z steeper than (1 +z)3.5. A shallower rate remains possible if the luminosity-weighted dust extinction at 2000 Å, as suggested by some data, is lower than ∼1.2.
