Burst Statistics Using the Lag-Luminosity Relationship

Abstract

Using the lag-luminosity relation and various BATSE catalogs we create a large catalog of burst redshifts, peak luminosities and emitted energies. These catalogs permit us to evaluate the lag-luminosity relation, and to study the burst energy distribution. We find that this distribution can be described as a power law with an index of alpha=1.76 +/- 0.05 (95% confidence), close to the alpha=2 predicted by the original quasi-universal jet model.
