Formation Rate, Evolving Luminosity Function, Jet Structure, and Progenitors for Long Gamma Ray Bursts

Abstract

We constrain the luminosity function and formation rate of long γ-ray bursts (GRBs) by using both the observed peak flux and redshift distributions. From our analysis, evidence supporting an evolution of the luminosity function is found. We compare the inferred GRB formation rate history to the cosmic star formation history up to z∼6. Some implications of… (More)
