Description
The Pierre Auger Observatory, the world’s largest extensive air-shower detector array, is optimized for the measurement of ultra-high-energy cosmic rays (UHECRs) and also provides sensitivity to ultra-high-energy neutrinos via detection of neutrino-induced air showers. Since the start of full operations in 2004, the Observatory has delivered key results in UHECR physics, including constraints on the energy spectrum, mass composition, and arrival direction anisotropies, and has become an important component of the multi-messenger astrophysics landscape.
The Observatory is integrated within the Astrophysical Center for Multi-messenger in Europe (ACME), an infrastructure initiative focused on enabling interoperable data access and enhancing coordination between major astroparticle facilities for time-domain and multi-messenger studies.
Within the ACME framework, the Pierre Auger Collaboration is currently expanding its open data strategy by increasing the accessibility of its archival datasets and developing capabilities for near-real-time analysis. In particular, ongoing developments target the implementation of a real-time alert system based on the identification of neutrino-induced and other highly inclined air-shower signatures, with the goal of enabling rapid multi-wavelength and multi-messenger follow-up observations.
This contribution will present the current status of ACME-related activities within the Pierre Auger Observatory, with emphasis on the extension of the public data infrastructure and the development and commissioning of the real-time alert pipeline.
