The highest energy neutrinos in IceCube

In searches for astrophysical neutrinos, either looking for events starting in the detector with a deposited energy larger than 100 TeV or throughgoing muons with a reconstructed muon energy larger than 200 TeV, IceCube has identified dozens of high-energy neutrinos. Those contain the highest-energy neutrino ever detected, with a deposited energy of 2.6 PeV and an estimated neutrino energy about three times greater.
