Determining the GRB (Redshift, Luminosity)-Distribution Using Burst Variability

Abstract
We use the possible Cepheid‐like luminosity estimator for the long‐duration gamma‐ray bursts (GRBs) developed by Reichart et al. (2000) to estimate the intrinsic luminosity, and thus the redshift, of 907 long‐duration GRBs from the BATSE 4B catalog. We describe a method based on Bayesian inference which allows us to infer the intrinsic GRB burst rate as a function of redshift for bursts with estimated intrinsic luminosities and redshifts. We apply this method to the above sample of long‐duration GRBs, and present some preliminary results.
