Description
The progenitors of high-energy (HE) neutrinos detected by the IceCube observatory (> 30 TeV) remain on the discussion. Astrophysical events such as Gamma-ray bursts (GRBs), Supernova remnants (SNR), Tidal disruption events, and Active galactic nuclei (AGN) are proposed as HE neutrinos progenitors. So far, the only detection in space-time coincidence with a neutrino event is by the TXS 0506+056 blazar with the neutrino IC 170822A, in whose case, the blazar was observed in flare state at different energy bands. We use ten years of data reported by Fermi-LAT in the 4LAC catalog and search for spatial and temporal correlations between these sources with the track neutrinos detected by IceCube. We propose that photo-hadronic interactions might explain some neutrino events and the spectral energy distribution of those sources.
