Oddball space neutrinos may be spawn of dark matter - physics-math - 15 August 2013 - New Scientist: ...apart from those seen after a 1987 supernova explosion, none had been detected from beyond the solar system...

Then, earlier this year, the IceCube collaboration...reported two deep-space neutrinos...

...expected sources of such neutrinos... should also produce neutrinos of energies different from those seen by IceCube so far...

They calculate that heavyweight dark matter particles of about 1 PeV would decay either directly into neutrinos of about 1 PeV, or into other particles and then into neutrinos with energies of tens of TeV. "It exactly reproduces the features that you see in IceCube," says Serpico...
