Abstract

The Pierre Auger Observatory is the result of an international effort of 17 countries, designed and built to study ultra high energy cosmic rays. Its main goal is to study cosmic rays of the highest energy observed so far, in the region of 1018 eV and above. These cosmic rays are the most energetic particles observed in nature up today. Experimental data obtained in the Observatory allow important steps in order to understand these cosmic rays and get clues about their origin, chemical composition, acceleration processes and propagation from their sources to Earth. The Pierre Auger Observatory is planned to be built at two sites, one in the northern and one in the southern hemisphere, in order to achieve full sky coverage. The southern site is located near the town of Malargüe, Argentina, and its construction was concluded in June 2008. The present project succeeds the previous one already supported by FAPESP (1999/05404-3) and aims to get support for the research activities of scientists from São Paulo in the Auger Collaboration, for their shifts in data taking at the Observatory and participation in international and national Collaboration Meetings, for covering the respective share of the operation costs of the Observatory in the next four years and also to allow the replacement of equipment at the southern site. It will also allow the participation of these scientists in the efforts for the Research and Development Array (RDA) of the northern site of the Observatory, near the town of Lamar, CO, USA. (AU)
