Recently, the IceCube Neutrino Observatory has alerted the astrophysical community about the detection of a very energetic neutrino event (called IceCube-170922A). Upon this alert, the Large Area Telescope (LAT) on board the Fermi Gamma-ray Space Telescope reported enhanced gamma-ray emission from BL Lac object TXS 0506+05, compatible with the direction of IceCube-170922A. The fact that this blazar was found in an elevated flux state at LAT energies at the time the 2017 neutrino event occured, motivated a possible association between the gamma-ray source and the neutrino event.
Using quasi-simultaneous multi-messenger data of TXS 0506+05, we present here generic model constraints for a photo-hadronic origin of the detected neutrino emission.
