IceCube results from point-like source searches using seven years of through-going muon data — •Stefan Coenders and Elisa Resconi for the IceCube collaboration — Technische Universität München, Boltzmannstr. 2, 85748 Garching
The IceCube Neutrino Observatory located at the geographic South Pole was designed to study and discover high-energy neutrinos coming from both galactic and extragalactic sources. Track-like events induced by charged-current muon-neutrino interactions close to the IceCube detector give an angular resolution better than 1 degree above TeV energies. Within seven years of detector livetime, IceCube selects more than 700,000 events over the full sky, plus an additional component of almost 1000 events that are identified to be starting in the detector in the southern sky. Using this event sample, IceCube is sensitive to a steady neutrino flux substantially below E2 ∂φ / ∂ E = 10−12 TeV cm−2 s−1 in the northern sky for neutrino energies above 10 TeV. We report about the results in this search for steady point-like neutrino sources.
