Abstract:
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 the peak luminosities by BeppoSAX and BATSE, and it looks
considerably tighter and more reliable than the relations suggested by
the previous works. Using the new Ep-luminosity relation, we
estimate redshifts of the 689 GRBs without known distances in the
BATSE catalog and derive a GRB formation rate as a function of the
redshift.
