Description
The origin of ultra-high-energy cosmic rays (UHECRs) is one of the most intriguing mysteries in astroparticle physics and high-energy physics. With an ability to select events by the rigidity $(E/Z)$, arrival directions of UHECRs can be exploited to probe the most extremely energetic phenomena in the universe. The Global Cosmic Ray Observatory (GCOS) is a proposed next-generation observatory to elucidate these origins through precise measurements of UHECRs with unprecedented exposure and mass identification capabilities. We will share ideas and requirements for GCOS summarized in https://arxiv.org/abs/2502.05657 and report the recent advances in detector developments and future perspectives.
