Multi-messenger studies at ultra-high energies with the Pierre Auger Observatory

Abstract content

The Pierre Auger Observatory is the world’s largest cosmic-ray detector, sensitive to cosmic rays with energy exceeding $\sim 10^{17}$ eV. In addition to charged cosmic rays that form the bulk of the cosmic-ray flux at ultra-high energies, Auger is sensitive to ultra-high energy neutral messengers (photons, neutrinos, and neutrons). The latter are particularly exciting as they are expected to arrive in spatial, and temporal coincidence with electromagnetic counterparts from the yet unknown sources of ultra-high energy cosmic rays, and can be used for triggering, or follow-up in multi-messenger transient searches. I will review the activities of Auger in a multi-messenger context, with focus on the searches for neutral particles in coincidence with gravitational wave events, multi-messenger cross-correlation searches, and realtime coincidence searches within the Astrophysical Multi-messenger Observatory Network (AMON).
