Long duration GRB Rate Page

Rate | Luminosity Function

Here I present an updated estimate of long GRB luminosity function, using the direct inversion method described in Wanderman and Piran 2010.

The above figure shows the luminosity function: the fraction of the bursts as a function of the isotropic equivalent luminosity (Liso) in a logarithmic scale.

The best fit is a broken power law: for < , for <,

Number of bursts in this sample: 124

The local GRB rate: 1.8 [yr^-1 Gpc^-3]
