GRBs with exponential decay in one hundred seconds as standard candles for Cosmology
Year: 2014
Type: preprint
Abstract: We identify a subclass of gamma-ray bursts whose prompt X-ray emission lasts for a few hundred seconds and shows a clear exponential decay over more than three orders of magnitude. We show that these events give-off roughly the same amount of energy in X-rays, and investigate their application in high redshift Cosmology. We discuss their potential association with the electromagnetic exponential spin down of the black hole that forms during the core collapse of a massive star, and evaluate the efficiency of high-energy production in the black hole magnetosphere.
