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 …

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 …

We present a detailed modeling and computation methodology to determine the optical
Cherenkov signals produced by upward-moving extensive air showers (EASs) induced by τ …

High-energy neutrino astronomy is a fascinating new field of research, rapidly developing
over recent years. It opens a new observation window on the most violent processes in the …

Abstract The balloon-borne ANITA [1] experiment is designed to detect ultra-high energy
neutrinos via radio emissions produced by in-ice showers. Although initially purposed for …

An overview of searches related to neutrinos of astronomical and astrophysical origin
performed within the framework of the Standard-Model Extension is provided. For this …

The propagation of ultra-high energy (UHE) cosmic rays (CRs) is affected by their
interactions with cosmic radiation backgrounds. Above an energy of GZK≃ 50 EeV CR …

Semiclassical processes such as production and decay of electroweak sphaleron in the
Standard Model and also microscopic black hole in low scale gravity scenario typically …
