Search for weak neutrino sources with an energy dependent autocorrelation analysis with IceCube in the northern sky — •Lisa Schumacher, Christian Haack, Martin Leuermann, Leif Rädel, René Reimann, Michael Schimp, Sebastian Schoenen, and Christopher Wiebusch — III.

The IceCube Neutrino Observatory located at the South Pole discovered a flux of astrophysical neutrinos. However, the sources of this flux have not been identified yet and strong sources are disfavored. Hence, this analysis searches for a distribution of weak, but numerous sources by employing an angular auto-correlation analysis using multipole expansion coefficients of spherical harmonics. It is optimized by using energy information to improve the significance of clustered astrophysical events with respect to diffuse backgrounds. Results from analyzing multiple years of muon neutrino data from IceCube are presented.
