A supermassive black hole, obscured by cosmic dust, powers the nearby active galaxy NGC
1068. Neutrinos, which rarely interact with matter, could provide information on the galaxy's …

Neutrino astronomy beyond the Sun was first imagined in the late 1950s; by the 1970s, it
was realized that kilometer-scale neutrino detectors were required. The first such instrument …

In the six decades following the discovery of the neutrino by Cowan and Reines [1],
detectors have been realized that have explored the properties and sources of neutrinos …

We present a measurement of the high-energy astrophysical muon–neutrino flux with the
IceCube Neutrino Observatory. The measurement uses a high-purity selection of650k …

The Glashow resonance describes the resonant formation of a W− boson during the
interaction of a high-energy electron antineutrino with an electron, peaking at an …

This Letter presents the results from pointlike neutrino source searches using ten years of
IceCube data collected between April 6, 2008 and July 10, 2018. We evaluate the …

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 …

The IceCube observatory located at the South Pole is a cubic-kilometre optical Cherenkov
telescope primarily designed for the detection of high-energy astrophysical neutrinos …

The detection of high-energy cosmic neutrinos as cosmic messengers has been an
important goal of astroparticle physics. Being stable, electrically neutral particles, high …

We report a quasidifferential upper limit on the extremely-high-energy (EHE) neutrino flux
above 5× 10 6 GeV based on an analysis of nine years of IceCube data. The astrophysical …
