Neutrino emission from gamma-ray bursts

Gamma-ray bursts (GRBs) are the most violent and energetic events in the universe. Short GRBs seem to be the result of the final merger of two compact objects, whereas long GRBs are probably associated with the gravitational collapse of very massive stars (collapsars). The central engine of a GRB c...
