“…Ultra-high-energy astrophysical neutrinos, above the PeV scale, are searched for in dedicated experiments (Aslanides et al 1999;Kestel 2004;Miocinovic et al 2004;Aggouras et al 2005;Arnold et al 2005;Silvestri 2005;Allison et al 2012;Barwick et al 2015) and in experiments designed to detect UHECRs (Rubtsov et al 2013;Aab et al 2015b;Bleve et al 2015;Supanitsky et al 2015). The IceCube Collaboration has detected neutrinos up to a few PeV (Aartsen et al 2013a(Aartsen et al , 2013b(Aartsen et al , 2014a(Aartsen et al , 2014b(Aartsen et al , 2015a(Aartsen et al , 2015b, likely produced on-site at unidentified astrophysical sources.…”

The origin and composition of ultra-high-energy cosmic rays (UHECRs) remain a mystery. The proton dip model describes their spectral shape in the energy range above 10 9 GeV by pair production and photohadronic interactions with the cosmic microwave background. The photohadronic interactions also produce cosmogenic neutrinos peaking around 10 9 GeV. We test whether this model is still viable in light of recent UHECR spectrum measurements from the Telescope Array experiment and upper limits on the cosmogenic neutrino flux from IceCube. While two-parameter fits have been already presented, we perform a full scan of the three main physical model parameters: source redshift evolution, injected proton maximal energy, and spectral index. We find qualitatively different conclusions compared to earlier two-parameter fits in the literature: a mild preference for a maximal energy cutoff at the sources instead of the Greisen-Zatsepin-Kuzmin cutoff, hard injection spectra, and strong source evolution. The predicted cosmogenic neutrino flux exceeds the IceCube limit for any parameter combination. As a result, the proton dip model is challenged at more than 95% C.L. This is strong evidence against this model independent of mass composition measurements.

“…In the Mediterranean sea, several efforts were started at different sites: the NESTOR project off the coast of Greece [14], the NEMO project close to Sicily [15] and the ANTARES neutrino telescope off the coast of France. While the first two projects made significant contributions to current and future deep-sea neutrino detector technology, the ANTARES collaboration has been operating a large-scale detector in stable conditions for several years.…”

With the recent discovery of high-energy neutrinos of extra-terrestrial origin by the IceCube neutrino observatory, neutrino-astronomy is entering a new era. The highest energy neutrinos observed to date exceed 1 PeV in energy, a regime of particular interest because the neutrinos should point back to the still elusive accelerators of the highest energy Galactic and extragalactic cosmic rays. This review will cover currently operating neutrino telescopes in water and ice, the latest results from searches for a flux of extra-terrestrial neutrinos and current efforts in the search for steady and transient neutrino point sources. In addition, future detectors such as KM3NeT in the Mediterranean Sea and plans for IceCube detector upgrades will be discussed.

“…NESTOR was conceived to consist of seven towers, each comprising 12 hexagonal floors, spread over a volume of 0.1 km 3 . In 2004, a single prototype floor was deployed and operated for about one month [29]. Its operation was terminated due to a failure of the cable to shore.…”

High-energy neutrino astronomy: a glimpse of the promised land

In 2012, physicists and astronomers celebrated the hundredth anniversary of the detection of cosmic rays by Viktor Hess. One year later, in 2013, there was first evidence for extraterrestrial highenergy neutrinos, i.e. for a signal which may contain key information on the origin of cosmic rays. That evidence is provided by data taken with the IceCube neutrino telescope at the South Pole. First concepts to build a detector of this kind have been discussed at the 1973 International Cosmic Ray Conference. Nobody would have guessed at that time that the march towards first discoveries would take forty years, the biblical time of the march from Egypt to Palestine. But now, after all, the year 2013 has provided us a first glimpse to the promised land of the neutrino universe at highest energies. This article sketches the evolution towards detectors with a realistic discovery potential, describes the recent relevant results obtained with the IceCube and ANTARES neutrino telescopes and tries a look into the future.
