The Pierre Auger Observatory, an example of cooperation in science and technology, involving over 400 scientists from 17 countries, including Romania, confirms the expansion of its activity until 2035.

The Pierre Auger experiment was in its second phase of operation with improved detectors, to increase the statistics of measured ultra-high-energy cosmic radiation events, and to answer fundamental questions such as: what are the sources of these energetic particles, and what is their chemical composition.

Romania has been a full Auger member country since 2014, and is currently represented by the Institute of Space Sciences - INFLPR Branch (ISS) and the National Institute of Physics and Nuclear Engineering "Horia Hulubei".

The ISS contribution to the Pierre Auger Collaboration is represented by activities such as: analysis of radio emission from cosmic ray bursts developed in the Earth's atmosphere, using modern high-performance computing and machine learning methods, to deduce the nature of cosmic radiation particles; support activities at the Collaboration's Monte Carlo service, for the production of libraries of simulated events, which serve for data analysis; participation in operational and monitoring shifts of remote Auger detectors from ISS-Romania, and last but not least, participation in the joint effort of education and awareness of science in society, by involving pupils and students in research practices.
