Description
The Pierre Auger Observatory, operated continuously since 2004, is the world’s largest cosmic-ray detector. It is designed to study the most energetic particles in the universe, has a unique capability to detect ultra-high-energy photons and neutrinos, and is sensitive also to physics beyond the standard model of particle physics.
This contribution will present the methods developed by the Pierre Auger Collaboration to search for photons and neutrinos in coincidence with astrophysical transient events, summarise their latest results and upper limits, and discuss how the Observatory contributes to multi-messenger studies by probing the most extreme astrophysical accelerators and testing models of cosmic-ray origin and propagation.
The Observatory is part of the Astrophysical Centre for Multi-messenger in Europe (ACME), an infrastructure initiative aimed at improving coordination and data exchange among major observatories. Access to data can be provided to external users by proposal-driven research projects.
