Follow-up of high-energy neutrino events in IceCube — •Martina Karl for the IceCube collaboration — Max Planck Institute for Physics, Munich, Germany — Technical University of Munich, Department of Physics, Garching, Germany

We investigate the arrival direction of the most energetic track-like neutrino events in IceCube. These high-energy events allow for a good pointing back to their origin direction and have a high probability to be of astrophysical origin. Roughly 10 of these track-like high-energy neutrino events are detected per year. With these events acting as a source catalog, we present a search for cosmic neutrino emission on 11 years of IceCube neutrino-induced muon data. We explore the hypotheses of steady and transient neutrino emission, and present methods to find neutrino flares.
