J/ApJ/609/935       Gamma-ray burst formation rate             (Yonetoku+, 2004)

Gamma-ray burst formation rate inferred from the spectral peak energy-peak luminosity relation. Yonetoku D., Murakami T., Nakamura T., Yamazaki R., Inoue A.K., Ioka K. <Astrophys. J., 609, 935-951 (2004)> =2004ApJ...609..935Y
ADC_Keywords: Gamma rays ; Redshifts Keywords: early universe - gamma rays: bursts 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. File Summary:
