Ultrahigh-energy cosmic rays (UHECRs) are atomic nuclei from space with vastly higher
energies than any other particles ever observed. Their origin and chemical composition …

An estimate of the expected photon flux above 10 17 eV from the interactions of ultra-high-
energy cosmic rays with the matter in the Galactic disk is presented. Uncertainties arising …

Upcoming neutrino telescopes may discover ultra-high-energy (UHE) cosmic neutrinos, with
energies beyond 100 PeV, in the next 10–20 years. Finding their sources would identify …

We measured the dipole of the diffuse γ-ray background (DGB), identifying a highly
significant time-independent signal coincidental with that of the Pierre Auger UHECR. The …

The cosmic-ray database, CRDB, has been gathering cosmic-ray data for the community
since 2013. We present a new release, CRDB v4. 1, providing many new quantities and …

We update the constraints on the location of the nearest ultrahigh energy cosmic ray
(UHECR) source. By analyzing recent data from the Pierre Auger Observatory using state-of …

Motivated by the detection of a significant dipole structure in the arrival directions of ultra-
high-energy cosmic rays above 8 EeV reported by the Pierre Auger Observatory (Auger), we …

We consider the possibility of explaining the observed spectrum and composition of the
cosmic rays with energies above 10 17 eV in terms of two different extragalactic populations …

Thanks to the high-quality data from the Pierre Auger Observatory [1], the world's largest
cosmic ray observatory, significant progress has been made in the quest to find the origin of …

IceCube-Gen2, the extension of the IceCube Neutrino Observatory, will feature three main
components: an optical array in the deep ice, a large-scale radio array in the shallow ice and …
