Search for Point Sources of High Energy Neutrinos with Final Data from AMANDA-II

Abstract

We present a search for point sources of high energy neutrinos using 3.8 years of data recorded by AMANDA-II during 2000-2006. After reconstructing muon tracks and applying selection criteria designed to optimally retain neutrino-induced events originating in the Northern Sky, we arrive at a sample of 6595 candidate events, predominantly from atmospheric neutrinos with primary energy 100 GeV to 8 TeV. Our search of this sample reveals no indications of a neutrino point source. We place the most stringent limits to date on $E^{-2}$ neutrino fluxes from points in the Northern Sky, with an average upper limit of $E^2{\Phi }_{{\nu }_{\mu }+{\nu }_{\tau }}\le$ 5.2 $\times$ 10${}^{-11}$ TeV cm${}^{-2}$ s${}^{-1}$ on the sum of ${\nu }_{\mu }$ and ${\nu }_{\tau }$ fluxes, assumed equal, over the energy range from 1.9 TeV to 2.5 PeV.
