The major activity of the HEA group at CWRU is experimental astrophysics research on the Pierre Auger Cosmic Ray Observatory. Auger is a collaboration of scientists from 17 different countries that have come together to construct the world's largest cosmic ray detector in Argentina. Our scientific goal is to understand the nature and the origins of cosmic rays. To learn more, visit the Auger page at CWRU.
