Beaming in Gamma-Ray Bursts: Evidence for a Standard Energy Reservoir
Beaming in Gamma-Ray Bursts: Evidence for a Standard Energy Reservoir
We present a comprehensive sample of all gamma-ray burst (GRB) afterglows with known distances, and we derive their conical opening angles based on observed broadband breaks in their light curves. Within the framework of this conical jet model, we correct for the geometry and we find that the gamma-ray energy …
