The realization that the total energy of gamma-ray bursts (GRBs) is correlated with their jet break angles motivates the search for a similar relation between the peak luminosity L and the jet break angles, L ∝ θ-2. Such a relation implies that the GRB luminosity function determines the angular distribution. We rederive the GRB luminosity function using the BATSE peak flux distribution and compare the predicted distribution with the observed redshift distribution. The luminosity function can be…

Quantifying the Luminosity Evolution in Gamma-Ray Bursts
We estimate the luminosity evolution and formation rate for more than 900 GRBs by using redshift and luminosity data calculated by Band, Norris, & Bonnell via the lag-luminosity correlation. By

We estimate a gamma-ray burst (GRB) formation rate based on the new relation between the spectral peak energy (Ep) and the peak luminosity. The new relation is derived by combining the data of Ep and

Recent evidence appears to link gamma-ray bursts (GRBs) to star-forming regions in galaxies at cosmological distances. If short-lived massive stars are the progenitors of GRBs, the rate of events per
