Some Seyfert galaxies are detected in high-energy gamma rays, but the mechanism and site of gamma-ray emission are unknown. Also, the origins of the cosmic high-energy neutrino …

We revisit constraints on decaying very heavy dark matter (VHDM) using the latest ultrahigh- energy cosmic-ray (UHECR; E≳ 10 18 eV) data and ultrahigh-energy (UHE) γ-ray flux upper …

We test the hypothesis of starburst galaxies as sources of ultrahigh energy cosmic rays and high energy neutrinos. The computation of interactions of ultrahigh energy cosmic rays in the …
In many models, the sources of ultrahigh-energy cosmic rays (UHECRs) are assumed to accelerate particles to the same maximum energy. Motivated by the fact that candidate …

We consider the prospects for future ultrahigh energy cosmic ray and neutrino observations to constrain the evolution of sources producing a proton flux above 10 EeV (1 EeV= 10 18 …

We use the surface detector of the Pierre Auger Observatory to search for air showers initiated by photons with an energy above 1019 eV. Photons in the zenith angle range from …

We present a measurement of the momentum spectra of π±, K±, p±, Λ, Λ¯, and KS 0 produced in interactions of negatively charged pions with carbon nuclei at beam momenta of …
