Description
The IceCube observations of neutrinos from two active galactic nuclei allow one to constrain the interactions of neutrinos with dark matter. The presence of a dark matter spike around the central supermassive black hole leads to limits on the scattering cross section that can exclude new regions of parameter space, depending upon the spike density profile and the energy-dependence of the cross section. The utility of the model-independent constraints is illustrated for dark photon mediators that couple to B-L.
