abstract

This contribution reviews recent advances in the possible identification of blazars as potential sources of at least some of the very-high-energy neutrinos detected by the IceCube neutrino detector at the South Pole. The basic physical requirements for neutrino production and physics constraints that may be drawn from neutrino - blazar associations are reviewed. Several individual cases of possible associations will be discussed in more detail. It is emphasized that due to $\gamma\gamma$ opacity constraints in efficiently neutrino-producing blazars, an association between X-ray -- soft $\gamma$-ray activity and very-high-energy neutrino production is more naturally expected than a connection between neutrino and high-energy/very-high-energy $\gamma$-ray activity.

  1. Did IceCube discover Dark Matter around Blazars?

    astro-ph.HE 2024-12 conditional novelty 6.0 of 10

    Sub-GeV dark matter scattering off protons in blazar jets can produce the IceCube neutrino from TXS 0506+056 while evading current dark matter constraints.

  2. IXPE Observation of the Low-Synchrotron Peaked Blazar S4 0954+65 During An Optical-X-ray Flare

    astro-ph.HE 2024-11 conditional novelty 6.0 of 10

    The first X-ray polarization observation of a flaring low-synchrotron-peaked blazar yields only an upper limit on X-ray polarization, which combined with spectral modeling tentatively disfavors hadronic X-ray emission.

  3. Polarisation as a probe of neutrino emission from blazars

    astro-ph.HE 2025-07 conditional novelty 5.0 of 10

    During a neutrino-associated flare, the blazar PKS 0735+178 showed rotations in radio and optical polarization angles consistent with a propagating shock, indicating conditions for proton-photon neutrino emission.
