Gamma-Ray Bursts : Discussion on the Log N-Log S Curve
Abstract
The spatial distribution of gamma-ray bursts is quasi-isotropic while the log N - log S curve does not comply with the S to the -3/2 power law, typical of an isotropic distribution. A model is described, wherein the maximum luminosity of the gamma-ray bursts, the index of the luminosity function power law, and the halo radius are used as free parameters. It is shown that the model agrees well with experimental data with either a halo radius of 20 Kpc, a maximum luminosity of 10 to the 42 ergs, and a luminosity index of 1.6 or a halo radius of 30 Kpc, a maximum luminosity of 10 to the 43 ergs, and a luminosity index of 2.0.
