The afterglows of the long and intermediate duration gamma-ray bursts

Author: József Kóbori

Abstract: We investigate the physical differences between the afterglows of the intermediate and long duration gamma-ray bursts using statistical methods. We find, that the temporal indices of long bursts in X-ray and optical bands are approximately similar, while in the cases of the itermediate bursts the X-ray lightcurves decay faster than the optical lightcurves.
