Neutrino emission in coincidence with gamma rays has been observed from the blazar TXS 0506+056 by the IceCube telescope. Neutrinos from the blazar had to pass through a dense spike of dark matter (DM) surrounding the central black hole. The observation of such a neutrino implies new upper bounds on the neutrino-DM scattering cross section as a function of DM mass. The constraint is stronger than existing ones for a range of DM masses, if the cross section rises linearly with energy. For constant cross sections, competitive bounds are also possible, depending on details of the DM spike.

Opening up New Parameter Space for Sterile Neutrino Dark Matter
A new production channel, nu_a + nu_a -> nu_s + nu_s, mediated by a heavy scalar, can generate the observed sterile neutrino dark matter abundance independently of active-sterile mixing.

Astrophysical Neutrino Sources as Colliders
Neutrino point-source observations (IceCube, KM3NeT) can bound inelastic pp and pγ cross sections from √s ≈ 1 GeV to ~10^5 GeV, extending beyond LHC/HERA and sometimes below unitarity limits.

Flavorful Interactions of AGN Neutrinos with Dark Matter Spike
IceCube-Gen2 flavor ratios can discriminate a U(1) neutrino–dark-matter model in AGN spikes from the standard (1/3:1/3:1/3) and muon-damped predictions, and, combined with mass-ordering and tau-decay data, constrain t...

Revisiting bounds on neutrino dark matter interaction at spikes
For light vector mediators, neutrino energy loss in dark-matter spikes is negligible, so cascade attenuation is suppressed by a small factor f and prior cross-section bounds are relaxed by 1/f.

The Highest-Energy Neutrino Event Constrains Dark Matter-Neutrino Interactions
KM3-230213A limits dark matter-neutrino scattering to below about 1e-22 cm^2/GeV at 220 PeV, but most simple dark matter models are excluded by unitarity above MeV masses.

Cosmological impact of $\nu$DM interactions enhanced in narrow redshift ranges
A redshift-limited dark matter-neutrino interaction reproduces the observed preference for non-zero coupling in CMB and cosmic shear data and evades small-scale structure bounds.

On the Blueprint of Active Galaxies Producing Neutrinos
Neutrinos from active galaxies are produced in compact X-ray-bright coronae within about ten Schwarzschild radii of the black hole, and such sources may supply the diffuse neutrino flux.
