Neutrino-blazar correlations: Striving for the big picture — •Martina Karl1, 2 and Matthias Huber2 for the IceCube collaboration — 1Max-Planck-Institut für Physik, Föhringer Ring 6, 80805München, Deutschland — 2Technische Universität München, Fakultät für Physik, James-Franck-Str. 1, 85748 Garching, Deutschland
The IceCube neutrino observatory experienced remarkable success in the field of neutrino astronomy since its completion. Besides the discovery of a diffuse astrophysical high-energy neutrino flux, IceCube found evidence for a correlation between high-energy neutrinos and the blazar TXS 0506+056 in 2018. Blazars, being a subclass of active galactic nuclei and consequently one of the most powerful objects in the universe are one of the most promising source candidates of high-energy neutrinos.
In this talk, we will present a correlation study between high-energy neutrinos measured with the IceCube neutrino detector and different classes of blazars. This study aims to provide the deepest understanding of the neutrino-blazar correlation that is accessible by means of current measurements.
