Gamma-ray burst beaming constraints from afterglow light curves.
RHOADS J.E.
Abstract (from CDS):
The beaming angle AFem is the main uncertainty in gamma ray burst energy requirements today. We summarize predictions for the light curves of beamed bursts, and model the R band light curve of GRB 970508 to derive AFem>30°. This yields an irreducible minimum energy requirement of 3.4x1049ergs to power the afterglow alone.
