Searches for neutrinos from GRBs using the ANTARES telescope

Multiple searches for neutrinos in correlation with gamma-ray bursts (GRBs) using data from the ANTARES neutrino telescope have been performed. One search uses data taken during 2007, at which time the telescope consisted of 5 detector lines, to measure the number of neutrino-induced muons in correlation with 37 GRBs that occurred during the data-taking period. While no correlations are observed, upper limits have been placed on the flux of neutrinos for different GRB models. A second search uses an alternative method to identify the shower at the neutrino-interaction vertex. This search is particularly sensitive to electron-neutrinos, but is able to observe neutrinos of any flavor. The sensitivity of this method to measure correlations between neutrinos and prompt photons emitted by GRBs is presented for a typical neutrino flux model.
