Off-axis emission from the beamed afterglow of gamma-ray bursts and a possible interpretation of the slowly declining X-ray afterglow of GRB 980425.


Abstract (from CDS):

A formula is derived for off-axis emissions from the beamed afterglow of gamma-ray bursts in a synchrotron model. The formula is applied to inhomogeneous circumstellar matter obeying n∝r–2, which is also suggested for SN 1998bw/GRB 980425. The slow decline rate as well as the X-ray flux, which is similar to the observed values, are obtained for an appropriate choice of parameters so that the association of GRB 980425 with SN 1998bw is further strengthened.
