High-energy cosmic rays are observed indirectly by detecting the extensive air showers
initiated in Earth's atmosphere. The interpretation of these observations relies on accurate …

In the last fifteen years radio detection made it back to the list of promising techniques for
extensive air showers, firstly, due to the installation and successful operation of digital radio …

High energy collisions at the High-Luminosity Large Hadron Collider (LHC) produce a large
number of particles along the beam collision axis, outside of the acceptance of existing LHC …

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 …

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

We report a measurement of the energy spectrum of cosmic rays above 2.5× 10 18 eV
based on 215 030 events. New results are presented: at about 1.3× 10 19 eV, the spectral …

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 …

A new analysis of the data set from the Pierre Auger Observatory provides evidence for
anisotropy in the arrival directions of ultra-high-energy cosmic rays on an intermediate …

We have searched for intermediate-scale anisotropy in the arrival directions of ultrahigh-
energy cosmic rays with energies above 57 EeV in the northern sky using data collected …

ABSTRACT The Telescope Array (TA) collaboration has measured the energy spectrum of
ultra-high energy cosmic rays (UHECRs) with primary energies above 1.6× 10 18 eV. This …
