The Subaru Hyper Suprime-Cam has documented cosmic-ray extensive air showers with remarkable accuracy.
While terrestrial showers offer us solace, cosmic showers captivate astrophysicists. Through their innovative approach, scientists at Osaka Metropolitan University have meticulously observed cosmic-ray extensive air showers, enabling a deeper understanding of the most potent particles in the Universe.
Unveiling the Hidden Capabilities of the Subaru Telescope
Upon the collision of a high-energy cosmic ray with Earth’s atmosphere, it triggers a vast array of particles, termed as an extensive air shower. A study helmed by Associate Professor Toshihiro Fujii from the Graduate School of Science and Nambu Yoichiro Institute of Theoretical and Experimental Physics at Osaka Metropolitan University, with the assistance of graduate scholar Fraser Bradfield, identified that the advanced camera mounted on the Subaru Telescope, located on Hawaii’s Mauna Kea volcano, can document these extensive air showers in exceptional detail.
The Subaru Telescope, initially conceptualized for astronomical observation, often detects cosmic rays as “tracks” on its images which, when obstructing the intended stars or galaxies, are generally disregarded as interferences in traditional astronomical data interpretation. Interestingly, this study concentrates on this so-called “interference.” By examining roughly 17,000 images taken from 2014 to 2020, the team identified 13 images showcasing extensive air showers, revealing an unusually high number of particle tracks.
A Paradigm Shift in Observational Techniques
Professor Fujii elucidated, “Traditional observational methodologies find it arduous to differentiate between the various particles that comprise extensive air showers. In contrast, our technique is poised to ascertain the specific characteristics of individual particles.”
Moreover, Professor Fujii stated, “By amalgamating our technique with standard methods, we aspire to enrich our comprehension of extensive air showers. This innovative approach could potentially aid in the quest for dark matter or other rare particles, thereby enhancing our grasp on the Universe’s transition to a period dominated by matter.”
The findings are scheduled to be published in Scientific Reports dated October 12, 2023.
