A New Distance Estimator and Spatial Distribution of Grbs Observed by Batse

We propose a redshift estimator for the long (T90 > 20) gamma-ray bursts (GRBs) observed by the BATSE. It is based on an empirical relation between the redshift and the power-law index of power density spectra (PDSs) of the observed GRBs. This relation is constructed by using the fact that the power-law index is dependent upon a characteristic timescale of… CONTINUE READING
