Description
The complementary information carried by cosmic rays, photons, neutrinos, and gravitational waves provides extremely valuable insights about individual cosmic sources and source populations. The Pierre Auger Observatory plays a central role in multi-messenger astronomy, and its results provide a deeper view of the properties of ultra-high cosmic rays. In this talk, we will review some of the most relevant results, such as the information implied by the energy spectrum, composition and anisotropies of the UHCR, and the latest results on photons and neutrinos. The data collected at the Observatory allow us to study the characteristics of hadronic interactions at energies unreachable at accelerators, and to test the existence of possible effects beyond the Standard Model of particles, such as the decay of super-heavy dark matter, or the violation of the Lorentz invariance. The perspectives opened by the AugerPrime upgrade of the observatory and its future contributions will be discussed.
