A number of anomalous results in short-baseline oscillation may hint at the existence of one
or more light sterile neutrino states in the eV mass range and have triggered a wave of new …

The discovery of high-energy astrophysical neutrinos and the first hints of coincident
electromagnetic and neutrino emissions opened new opportunities in multi-messenger …

The origin of high-energy cosmic rays, atomic nuclei that continuously impact Earth's
atmosphere, is unknown. Because of deflection by interstellar magnetic fields, cosmic rays …

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 …

The observation of electromagnetic radiation from radio to γ-ray wavelengths has provided a
wealth of information about the Universe. However, at PeV (10 15 eV) energies and above …

The IceCube Neutrino Observatory has established the existence of a high-energy all-sky
neutrino flux of astrophysical origin. This discovery was made using events interacting within …

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 …

INTRODUCTION Neutrinos are tracers of cosmic-ray acceleration: electrically neutral and
traveling at nearly the speed of light, they can escape the densest environments and may be …

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 report on the first measurement of the astrophysical neutrino flux using particle showers
(cascades) in IceCube data from 2010–2015. Assuming standard oscillations, the …
