Search for Neutrino from Gamma-Ray Bursts with the ANTARES Telescope
Résumé
Gamma-ray bursts (GRBs) are powerful cosmic particle accelerators producing a highly
variable flux of high energy gamma-rays. Under the assumption of hadronic acceleration in jets, a
copious flux of neutrinos can be expected. Among the possible astrophysical sources, GRBs offer
one of the most promising perspectives for the detection of cosmic neutrinos thanks to an almost
background free search. The ANTARES neutrino telescope is running in a completely finished state
since May 2008. The collaboration has implemented two different methods to search for GRBs: the
first one is based on the search for neutrino candidates relying on the time and position information
provided by an external trigger and the second one is based on the optical follow-up of special
neutrino events. The use of these two complementary techniques provides enhanced sensitivity to
transient sources.
