High-energy neutrino astronomy with IceCube: recent results and new perspectives — •Kai Krings for the IceCube collaboration — Technische Universität München, Physik-Department, James-Franck-Str. 1, 85748 Garching

Building a neutrino telescope at the Geographic South Pole was envisioned in the end of the 80s. After the first in-ice detection of neutrinos from the Earth's atmosphere with its predecessor AMANDA in the year 2000, the IceCube Neutrino Observatory was completed in 2011. IceCube is a one cubic kilometer sized deep in-ice Cherenkov telescope. It is composed by 5160 digital optical modules that record the Cherenkov light emitted along secondary charged particles, which are produced in neutrino interactions with the Antarctic ice. First high-energy neutrino events of astrophysical origin were discovered in 2013. A new phase of neutrino astronomy in Antarctica was initiated with the first evidence for a non-stellar neutrino point source in 2018: a high-energy neutrino-induced muon track was observed from the direction of the blazar TXS0506+056 and in coincidence with very high-energy gamma rays from the same direction. Moreover, a follow-up search found in the archival IceCube data evidence for a neutrino flare from the direction of TXS0506+056. In this group talk, we will report on recent IceCube results connected to high-energy neutrino astronomy and introduce a possible path towards the future of this new field.
