An important radiation field for photomeson neutrino production in blazars is shown to be the radiation field external to the jet. Assuming that protons are accelerated with the same power as electrons and injected with a -2 number spectrum, we predict that km^2 neutrino telescopes will detect about 1-to-several neutrinos per year from flat spectrum radio quasars (FSRQs) such as 3C 279. The escaping high-energy neutron and photon beams transport inner jet energy far from the black-hole engine, and could power synchrotron X-ray jets and FR II hot spots and lobes.

  1. Multi-messenger tests of cosmic-ray acceleration in radiatively inefficient accretion flows

    astro-ph.HE 2019-08 conditional novelty 6.0 of 10

    Nearby low-luminosity active galactic nuclei with radiatively inefficient accretion flows should emit detectable MeV gamma rays and TeV-PeV neutrinos for future instruments, provided protons are accelerated with the a...

  2. Can a gamma-ray dim radio blazar produce a 200-PeV neutrino? The case of PMN J0606$-$0724 and KM3-230213A

    astro-ph.HE 2025-09 conditional novelty 5.0 of 10

    A gamma-ray dim radio blazar, PMN J0606-0724, can plausibly explain the 200 PeV KM3NeT neutrino through proton-photon interactions in its radio core, with the associated gamma rays absorbed internally.

  3. TeV-PeV Gamma-ray and Neutrino Emission in the Galactic Plane

    astro-ph.HE 2026-06 unverdicted novelty 3.0 of 10

    Alternative ISRF models produce only modest changes to the LHAASO diffuse gamma-ray fit; the associated pp neutrinos remain consistent with IceCube all-sky data and compatible with ANTARES/KM3NeT limits.

    astro-ph.HE 2026-06 unverdicted novelty 2.5 of 10

    Review summarizing correlations between astrophysical neutrinos and gamma-ray/radio AGN, specific source associations, proposed production mechanisms, and future prospects.
