This is also the case for the search of a Galactic component in the diffuse neutrino flux observed so far ( Adrian-Martinez, 2016a Aartsen, 2017b). Searches for point sources associated with these, or any other point sources, in the sky have come up empty so far ( Aartsen, 2017b Adrian-Martinez, 2015b Aartsen, 2017a Adrian-Martinez, 2013). The speculations are very much centered on powering the accelerator by tapping the gravitational energy of supermassive black holes in active galactic nuclei (AGN) and, alternatively, of the collapse of a massive star into a black hole in a gamma ray burst (GRB). Accounting for the enormous luminosity and energy of the extragalactic cosmic rays observed has been challenging to the point that few compelling ideas have emerged. Astrophysical neutrinos are one of the by-products of cosmic ray accelerators. The origin of the diffuse high-energy neutrino emission observed with IceCube is so far unknown. The future of neutrino astronomy looks bright. The large extragalactic flux observed implies that the energy density of neutrinos matches the one observed in photons indicating a much larger role of proton accelerators in the high-energy universe. A population of cosmic neutrinos covering the 30 TeV–1 PeV energy region were revealed by the first two years of IceCube data. Kilometer-scale neutrino observatory, IceCube.

In full operation since 2000, it represented a proof of concept for the Ice into a particle detector, the Antarctic Muon and Neutrino Detector Array (AMANDA). These efforts in turn have led towards the ongoing construction of KM3NeT off the coast of Italy and GVD in Lake Baikal.īut the first telescope on the scale envisaged by the DUMAND collaboration was realized instead by transforming a large volume of transparent natural Antarctic In use today, and by inspiring the deployment of a smaller instrument in Lakeīaikal (Russia) as well as efforts to commission neutrino Paved the way for later efforts by pioneering many of the detector technologies After a two-decade-long effort, building theĭeep Underwater Muon and Neutrino Detector (DUMAND) in the sea off the main Produced when neutrinos interact with nuclei in or near theĭetector.

Large volumes of natural water into Cherenkov detectors that collect the light Given the detector’s required size, early efforts concentrated on transforming It was already realized in the early 1970s that immense particle detectors are required to collect cosmic neutrinos in statistically significant numbers. But, their weak interactions also make cosmic neutrinos veryĭifficult to detect. Neighborhood of black holes and from the nuclear furnaces whereĬosmic rays (CRs) are born. Neutrinos may reach us unscathed from cosmic distances: from the close Having essentially no mass and no electricĬharge, the neutrino is similar to the photon as an astronomical messenger, except for one important attribute: its interactions with matter are extremely feeble. Neutrinos travelįrom the edge of the Universe without absorption and with noĭeflection by magnetic fields. Soon after the 1956 observation of the neutrino, the ideaĮmerged that it represented the ideal astronomical messenger.
