Search for point-like sources using the diffuse astrophysical muon-neutrino flux in IceCube — •René Reimann, Christian Haack, Leif Rädel, Sebastian Schoenen, Lisa Schumacher, and Christopher Wiebusch for the IceCube collaboration — III. Physikalisches Institut B, RWTH Aachen

IceCube, a cubic-kilometer sized neutrino detector at the geographic South Pole, has recently confirmed a flux of high-energy astrophysical neutrinos in the track-like muon channel. Although this muon-neutrino flux has now been observed with high significance, no point sources or source classes could be identified yet with these well pointing events. We present a search for point-like sources based on a six year sample of upgoing muon-neutrinos with very low background contamination. To improve the sensitivity, the standard likelihood approach has been modified to focus on the properties of the measured astrophysical muon-neutrino flux.
