Available in PDF, EPUB and Kindle. Book excerpt: 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 E2?{sub?{sub {mu}}+?{sub {tau}}} ≤ 5.2 x 10−11 TeV cm−2 s−1 on the sum of?{sub {mu}} and {nu}{sub {tau}} fluxes, assumed equal, over the energy range from 1.9 TeV to 2.5 PeV.
