This review demonstrates the unique role of the neutrino by discussing in detail the physics
of and with neutrinos. We deal with neutrino sources, neutrino oscillations, absolute masses …

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

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 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 …

Abstract The Probe Of Extreme Multi-Messenger Astrophysics (POEMMA) is designed to
accurately observe ultra-high-energy cosmic rays (UHECRs) and cosmic neutrinos from …

The present white paper is submitted as part of the “Snowmass” process to help inform the
long-term plans of the United States Department of Energy and the National Science …

Astrophysical neutrinos are excellent probes of astroparticle physics and high-energy
physics. With energies far beyond solar, supernovae, atmospheric, and accelerator …

Observational information on high-energy astrophysical neutrinos is being continuously
collected by the IceCube observatory. However, the sources of the neutrinos are still …

A bstract We compute the decay spectrum for dark matter (DM) with masses above the scale
of electroweak symmetry breaking, all the way to the Planck scale. For an arbitrary hard …

In this work we present the interpretation of the energy spectrum and mass composition data
as measured by the Pierre Auger Collaboration above 6× 1017 eV. We use an astrophysical …
