Description
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.
