EVIDENCE OF BULK ACCELERATION OF THE GRB X-RAY FLARE EMISSION REGION

ABSTRACT Applying our recently developed generalized version of the high-latitude emission theory to the observations of X-ray flares in gamma-ray bursts (GRBs), here we present clear observational evidence that the X-ray flare emission region is undergoing rapid bulk acceleration as the photons are...
