This review provides a perspective on the use of orbital-dependent functionals, which is
currently considered one of the most promising avenues in modern density-functional …

In this paper we review air shower data related to the mass composition of cosmic rays
above 1015eV. After explaining the basic relations between air shower observables and the …

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 …

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

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

This biennial Review summarizes much of particle physics. Using data from previous
editions, plus 2158 new measurements from 551 papers, we list, evaluate, and average …

The origin of the highest energy cosmic rays is still unknown. The discovery of their sources
is expected to reveal the workings of the most energetic astrophysical accelerators in the …

We study high-energy neutrino production in inner jets of radio-loud active galactic nuclei
(AGN), taking into account effects of external photon fields and the blazar sequence. We …

We report on studies of the viability and sensitivity of the Askaryan Radio Array (ARA), a new
initiative to develop a Teraton-scale ultra-high energy neutrino detector in deep, radio …

We calculate the prompt neutrino flux from atmospheric charm production by cosmic rays,
using the dipole picture in a perturbative QCD framework, which incorporates the parton …
