Abstract:
Gamma-ray bursts (GRBs), the most powerful
objects in the Universe, are believed to be associated with core-collapse
supernovae that lead directly to the creation of a black hole and with
mergers of binary compact objects. They are also one of the prime
candidates for the source of the highest energy cosmic rays. Thus, GRBs are excellent phenomena to be studied with
neutrinos and high energy gamma-rays. Searches for neutrinos have so far
been negative while photons of up to 30 GeV have
been observed by Fermi. In this talk I will review the prospects for
detection of high energy emission by the IceCube
neutrino telescope and the HAWC gamma-ray
detector. I'll also provide a brief summary of the observations and
capabilities of related detectors.
