Pierre Auger Observatory celebrates this year the 20th Anniversary. The Scientific Symposium, Science Fair and official Celebration take place in Malargüe (Province Mendoza, Argentina), during November 14th -16th, 2019, at the site of the Pierre Auger Observatory.
The Pierre Auger Observatory is the world-wide largest cosmic ray detector, covering an area of 3000 km2. It is operated by a collaboration of more than 400 scientists from 17 countries (including Romania since 2014, represented presently by IFIN-HH and ISS). The aim of the Observatory is the study of the highest-energy particles of the cosmos, up to 1020 electronvolts and above. Data of the Auger Observatory led to major advances in our understanding of high-energy phenomena linked to the most violent processes in the Universe. Scientific breakthroughs have been achieved in several fields. Still, the sources of the particles of such extreme energies have not been identified. In addition, the properties of multiparticle production are studied at energies not covered by man-made accelerators searching for new or unexpected changes of hadronic interactions. The currently ongoing upgrade of the Pierre Auger Observatory, called AugerPrime, will help to address also those remaining open questions and will favor the emergence of a uniquely consistent picture.
