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

Multimessenger astronomy has become increasingly important during the past decade.
Some astronomical objects have already been successfully observed in the light of multiple …

Experimental observations of extensive air showers have revealed a deficit of the muon
content in their theoretical simulations. This hampers a precise determination of the ultra …

One of the key challenges in astroparticle physics is the identification of the sources of
cosmic rays at the highest energies (above 10 18 eV). In this context, the search for neutral …

Blazars are a class of Active Galactic Nuclei (AGN) that are radio loud and have a small
angle between the jet and the observer's line of sight, found in the centres of elliptical …
