Description
Over the last few years the IceCube Neutrino Telescope has reported the first observations of an high-energy astrophysical neutrino flux. Recently, these observations have been strengthened by the publication of a sample of 82 high-energy starting events (HESE), and 36 high-energy muon neutrino tracks. Many different scenarios for the astrophysical origin of the IceCube neutrinos have been explored, but no clear answer has yet emerged. Among the possible sources, blazars are so far the most supported by the data, nevertheless their maximum contribution to the astrophysical neutrino flux has been constrained to be less than 27 per cent. We consider here a new, possible contributing class of neutrino emitters: AGN Outflows. We present here the results of quantitative tests, exploring the possible connection between IceCube neutrinos and AGN objects displaying outflows or outflow-like properties.
