PeV neutrinos observed by IceCube from cores of active galactic nuclei
Recently, the IceCube Collaboration has reported the first observation of cosmic 2 PeV energy neutrinos giving a signal 3 above the atmospheric background [1]. More recently, 18 events 4 above the expected atmospheric background were reported with energies above 100 TeV. These neutrinos are likely to be of cosmic origin; their angular distribution is consistent with isotropy. The average spectr...
متن کاملPhysics with Cosmic Neutrinos, Pev to Zev
Neutrinos offer a particularly promising eye on the extreme Universe. Neutrinos are not attenuated by intervening radiation fields such as the Cosmic Microwave Background, and so they are messengers from the very distant and very young phase of the universe. Also, neutrinos are not deflected by cosmic magnetic fields, and so they should point to their sources. In addition, there are particle ph...

متن کاملFirst observation of PeV-energy neutrinos with IceCube.
We report on the observation of two neutrino-induced events which have an estimated deposited energy in the IceCube detector of 1.04±0.16 and 1.14±0.17 PeV, respectively, the highest neutrino energies observed so far. These events are consistent with fully contained particle showers induced by neutral-current ν(e,μ,τ) (ν(e,μ,τ)) or charged-current ν(e) (ν(e)) interactions within the IceCube det...
متن کاملTeV Neutrinos from Galactic Microquasar Jets
We discuss the possibility that microquasar jets may be powerful emitters of TeV neutrinos. We estimate the neutrino fluxes produced by photopion production in the jets of a sample of identified microquasars and microquasar candidates, for which available data enables rough determination of the jet parameters. We demonstrate that in several of the sources considered, the neutrino flux at Earth,...
