The presence of a high-energy neutrino flux containing the most energetic neutrinos ever observed is revealed, including 28 events at energies between 30 and 1200 TeV, although the origin of this flux is unknown and the findings are consistent with expectations for a neutRino population with origins outside the solar system.

Results from an analysis with a third year of data from the complete IceCube detector are consistent with the previously reported astrophysical flux in the 100 TeV-PeV range at the level of 10(-8) GeV cm-2 s-1 sr-1 per flavor and reject a purely atmospheric explanation for the combined three-year data at 5.7σ.

These two neutrino-induced events could be a first indication of an astrophysical neutrinos flux; the moderate significance, however, does not permit a definitive conclusion at this time.

The IceCube Neutrino Observatory was designed primarily to search for high-energy (TeV-PeV) neutLrinos produced in distant astrophysical objects. A search for. greater than or similar to 100 TeV…
Measurement of day and night neutrino energy spectra at SNO and constraints on neutrino mixing parameters.
- Q. Ahmad, R. C. Allen, M. Yeh

- 1 July 2002
The Sudbury Neutrino Observatory (SNO) has measured day and night solar neutrino energy spectra and rates, and a global solar neutRino analysis in terms of matter-enhanced oscillations of two active flavors strongly favors the large mixing angle solution.
