Search for small-scale anisotropies with four years of IceCube — •Anna Bernhard für die IceCube Kollaboration — TU München

The IceCube neutrino observatory build in the antarctic ice offers unique opportunities in studying high energy neutrino emission from galactic and extragalactic sources. Detecting such neutrino emission could give invaluable information about the origin of cosmic rays. Recently, first evidence for astrophysical neutrinos in the PeV range was found with IceCube. Another promising way to get insight into the cosmic ray production is the study of an event clustering at small scales for high-energy neutrinos. We will report about a complementary search for multiple neutrino point sources with four years of IceCube data, performing an autocorrelation test on the full sky. In addition, we will present an autocorrelation analysis of the Cygnus region, which is a promising area in terms of star formation and therefore a particularly interesting target for high-energy neutrinos. For both searches the expected sensitivites and discovery potentials will be shown.
