Research output: Contribution to journalArticlepeer-review


In the generic gamma-ray burst model cosmic rays can be accelerated up to GZK energies of ∼ 1020 eV. providing a flux comparable to that detected at those energies by arrays such as AUGER. Both common leptonic processes such as electron synchrotron and inverse Compton, as well as photomeson processes, can lead to GeV to TeV gamma-rays, which are measurable by GLAST and AGILE, providing probes of the gamma-ray burst physics and model parameters. Photomeson interactions can also produce neutrinos at energies ranging from sub-TeV to EeV, which would yield interesting physical information about fundamental interactions, about the sources ability to accelerate cosmic rays, and about the nature of the sources and their environment. The expected neutrino emission and its physical implications can be addressed with a number of forthcoming experiments such as IceCube, ANITA and KM3NeT.
