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 …

Galaxy clusters are the largest objects in the Universe kept together by gravity. Most of their
baryonic content is made of a magnetized diffuse plasma. We investigate the impact of such …

Soon, a new generation of neutrino telescopes, presently under planning, will target the
discovery of ultra-high-energy (UHE) neutrinos of cosmic origin, with energies higher than …

Context. Jets of active galactic nuclei are potential accelerators of ultra high-energy cosmic
rays. Supernovae can occur inside these jets and contribute to cosmic ray acceleration …

Knowledge of the primary composition of cosmic rays is very important for understanding the
nature and origin of ultra-high-energy cosmic rays (UHECR). As cosmic rays propagate …

The challenge of explaining the origin of ultra-high-energy cosmic rays (UHECRs) is the
need for a source class that can accelerate particles up to 100 EeV and that is abundant …

Ultra-high-energy cosmic rays (UHECRs) persist as an area of profound investigation, with
the quest to unveil their origin on the brink of realization. Recent findings indicate a potential …

We report on several new results using anisotropies of UHECRs. We improve and extend
the work of Ding, Globus and Farrar, who modeled the UHECR dipole assuming sources …

The Pierre Auger Observatory is a unique facility designed to study ultra-high energy cosmic
rays, with energies up to 10$^{20} $ eV and beyond. The Observatory is located in Argentina …

The Pierre Auger Collaboration has embraced the concept of open access to their research
data since its foundation, with the aim of giving access to the widest possible community. A …
