Radio-to-gamma-ray Synchrotron and Neutrino Emission from Proton-proton Interactions in Active Galactic Nuclei

We explore possible physical origin of correlation between radio wave and very-high-energy neutrino emission in active galactic nuclei (AGN), suggested by recently reported evidence for correlation between neutrino arrival directions and positions of brightest radio-loud AGN. We show that such correlation is expected if both synchrotron emitting electrons and neutrinos originate from decays of charged pions produced in proton-proton interactions in parsec-scale relativistic jet propagating through circum-nuclear medium of the AGN.

Automated summary

The study explores the possible physical origin of the correlation between radio wave and very-high-energy neutrino emissions in AGNs, indicating that this correlation is expected to arise from the decays of charged pions produced in proton-proton interactions in parsec-scale relativistic jets.
