Search for the origin of the diffuse extra-terrestrial(pdf)

IceCube is the world's largest high-energy neutrino observatory, built at the South Pole. IceCube detects neutrinos via the Cherenkov-light of charged secondary particles, that are produced in neutrino interactions with nuclei of the antarctic ice. Recently, the IceCube Collaboration has reported the observation of a diffuse high-energy astrophysical neutrino flux. However, IceCube has not yet found any significant clustering of neutrino events or correlation with any astrophysical objects. The identification of sources of the measured diffuse flux may be achieved by use of the excellent pointing of high-energy muons from muon-neutrino interactions. I will summarize the current status of standard searches for point-like sources of high-energy neutrinos with IceCube. Further, I will present an outlook on new methods for a multi-year point-source search.
