The followup of IceCube alerts: Search for high-energetic neutrino sources — •Anna Schubert¹ and Martina Karl^{1, 2} for the IceCube collaboration — ¹Technische Universität München, Fakultät für Physik, James-Franck-Str. 1, 85748 Garching, Deutschland — ²Max-Planck-Institut für Physik, Föhringer Ring 6, 80805 München, Deutschland

IceCube is a cubic-kilometer scale neutrino detector instrumenting a gigaton of ice at the geographic South Pole in Antarctica. On average, 8 track-like high energetic neutrino events with a high probability of being of astrophysical origin are detected per year. The bright appearance of these events in the detector allows for a good pointing to their origin. In this talk we present a search for the production sites of these cosmic neutrinos and hence also of the closely connected high-energy cosmic-rays. We use IceCube's high-statistics, neutrino-induced through-going muon samples to search for sources specifically in the vicinity of the arrival directions of the single most high-energetic events. The analysis searches for both, steady sources as well as for sources that only temporarily produce neutrinos.
