Observations of high energy neutrinos with water/ice neutrino telescopes

Abstract

The search for high energy neutrinos of astrophysical origin is being conducted today with two water/ice Cherenkov experiments. New instruments of higher performance are now in construction and more are in the R&D phase. No sources have been found to date. Upper limits on neutrino fluxes are approaching model predictions. Results are reported on the search for point sources, diffuse fluxes, gamma ray bursts, dark matter and other sources.
