Luminosities and space densities of gamma-ray bursts.

SCHMIDT M.

Abstract (from CDS):

We use a homogeneous sample of gamma-ray bursts (GRBs) extracted from 5.9 yr of BATSE DISCLA data and a variety of assumed broken power-law luminosity functions to derive GRB luminosities and space densities. Luminosity functions that are narrow or exhibit no density evolution produce expected redshift distributions that are incompatible with the observation of a GRB redshift of 3.4. For q₀=0.1 and density evolution rising to 10 at z=1, we find for a variety of slopes of the luminosity function values of the local space density around 0.18 Gpc^–3.yr^–1 with a range of only 40%. Characteristic 50-300 keV peak luminosities exhibit a range of a factor of 6 around 6x10⁵¹ ergs.s^–1, corresponding to a characteristic total luminosity of 1.2x10⁵³ ergs in the 10-1000 keV band. For q₀=0.5, densities are higher and luminosities lower, both by a factor of 2.5. The local emissivity of GRBs is 1.0x10⁵² ergs.Gpc^–3.yr^–1 in the 10-1000 keV band.
