Evidence for High-Energy Extraterrestrial Neutrinos at the IceCube Detector

IceCube Collaboration, Aartsen, M. G., Abbasi, R. et al.

Understand

We report on results of an all-sky search for high-energy neutrino events interacting within the IceCube neutrino detector conducted between May 2010 and May 2012.

The search follows up on the previous detection of two PeV neutrino events, with improved sensitivity and extended energy coverage down to approximately 30 TeV.
Twenty-six additional events were observed, substantially more than expected from atmospheric backgrounds.
Combined, both searches reject a purely atmospheric origin for the twenty-eight events at the $4\sigma$ level.
