The IceCube Collaboration recently announced the detection of a high-energy astrophysical neutrino consistent with arriving from the direction of the blazar TXS 0506+056 during an energetic gamma-ray flare, and a “neutrino flare” from the same direction during 2014-15. I will present some of the inferences drawn from these observations for neutrino emission from TXS 0506+056, in light of the...

We present a systematic study of the feasibility of photo-hadronic
production of IceCube neutrinos in the jet of the BL Lac object
TXS 0506+056 during the extended 2014 - 2015 neutrino flare. Starting
with the measured neutrino flux and spectrum, we study the effect of
electromagnetic cascades initiated by pion decay, necessarily
accompanying neutrino production. Depending on the...

Among the various categories of Active Galactic Nuclei (AGN), Blazars are the most promising sources of TeV/PeV neutrinos, due to their high luminosity at very high-energy (VHE) range during the active periods. After the multi-wavelength observation of the TXS0506+056, with a extreme high energy (EHE) event of IceCube followed-up by a significant flaring emission registered by Fermi-LAT and...

High-fluence outbursts in coincidence with IceCube neutrino events have been found for the blazars PKS 1424-418 and TXS 0506+056. Here, we study all 179 3LAC blazars consistent with HESE IceCube neutrinos above 100 TeV and below 1 PeV. Adopting the IceCube neutrino spectral index, we compute the expected neutrino event numbers. We emphasize that the calorimetric photon energy fluxes obtained...

Blazar jets are extreme environments, in which relativistic proton interactions with a UV photon field could give rise to photopion production. High-confidence associations of individual high-energy neutrinos with blazar flares could be achieved via spatially and temporally coincident detections.
Recently, the track-like, extremely high energy neutrino event IceCube-170922A was found to...
