Neutrino astronomy and gamma-ray bursts.
The construction of large-volume detectors of high energy, greater than 1TeV, neutrinos is mainly driven by the search for extragalactic neutrino sources. The existence of such sources is implied by the observations of ultra-high-energy, greater than or equal to 1019eV, cosmic rays, the origin of which is a mystery. In this lecture, I briefly discuss the expected extragalactic neutrino signal a...
متن کاملNeutrino Event Rates from Gamma-Ray Bursts.
We recalculate the diffuse flux of high-energy neutrinos produced by gamma-ray bursts in the relativistic fireball model. Although we confirm that the average single burst produces only approximately 10-2 high-energy neutrino events in a detector with a 1 km2 effective area, i.e., about 10 events yr-1, we show that the observed rate is dominated by burst-to-burst fluctuations that are very larg...
متن کاملPrompt Neutrino Emission from Gamma-Ray Bursts
Recent observations show that some or possibly all long-duration gamma-ray bursts (GRBs) arise from the core collapse of massive stars. In this case, the GRB environments are believed to be preburst stellar winds. We here study prompt neutrino emission from reverse shocks as a result of the interaction of relativistic fireballs with their surrounding wind matter. We find that for reasonable par...
متن کاملNeutrino Tomography of Gamma Ray Bursts and Massive Stellar Collapses
Neutrinos at energies above TeV can serve as probes of the stellar progenitor and jet dynamics of gamma ray bursts arising from stellar core collapses. They can also probe collapses which do not lead to gamma-rays, which may be much more numerous. We calculate detailed neutrino spectra from shock accelerated protons in jets just below the outer stellar envelope, before their emergence. We prese...
متن کاملNeutrino Afterglows and Progenitors of Gamma-Ray Bursts
Currently popular models for progenitors of gamma-ray bursts (GRBs) are the mergers of compact objects and the explosions of massive stars. These two cases have distinctive environments for GRBs: compact object mergers occur in the interstellar medium (ISM) and the explosions of massive stars occur in the preburst stellar wind. We here discuss neutrino afterglows from reverse shocks as a result...
