While there is evidence for the existence of dark matter, its properties have yet to be discovered. Simultaneously, the nature of high-energy astrophysical neutrinos detected by IceCube remains unresolved. If dark matter and neutrinos are coupled to each other, they may exhibit a non-zero elastic scattering cross section. Such an interaction between an isotropic extragalactic neutrino flux and dark matter would be concentrated in the Galactic Centre, where the dark matter column density is… Expand

Imaging Galactic Dark Matter with High-Energy Cosmic Neutrinos.
TLDR
It is found that IceCube can probe regions of the parameter space inaccessible to current cosmological methods, and an extended unbinned likelihood analysis is performed using the four-year high-energy starting event data set to constrain the strength of DM-neutrino interactions for two model classes.
