• Pierre Auger Observatory Project

The Pierre Auger Observatory, located in Malargüe, Mendoza Province, is an international collaboration project aimed at studying high-energy cosmic rays. In this context, the group has had a significant impact since the project's inception in activities related to management, installation, and operation of detectors, surface event reconstruction codes, analysis of arrival directions, very low-energy studies (space weather), and the research and development phase of the Observatory's Upgrade.
