Abstract

The origin of Ultra-High Energy Cosmic Rays (UHECR) is a long-standing mystery. These extraordinary particles, with energies up to ten-millions times higher than those achieved in particle accelerators, are so rare that their detection required the construction of the Pierre Auger Observatory, covering 3000 square kilometers in Argentina. The world’s largest cosmic ray detector has recently completed an upgrade,…
