Abstract

Very long and precise follow-up measurements of the x-ray afterglow of very intense gamma-ray bursts (GRBs) allow a critical test of GRB theories. Here we show that the single power-law decay with time of the x-ray afterglow of GRB 130427A, the record-long and most accurately measured x-ray afterglow of an intense GRB by the Swift, Chandra, and XMM-Newton space observatories, and of all other known intense GRBs, is that predicted by the cannonball model of GRBs from their measured spectral index, while it disagrees with that predicted by the widely accepted fireball models of GRBs.
