Dark Matter and Cosmology
Cosmology is the study of the structure, origin, and formation of the universe. Thanks to the wide-field imaging capability at the prime focus, the Subaru Telescope makes important and continuing contributions to the observational cosmology. For example, scientists revealed the distribution of dark matter using Subaru’s wide and deep data. The expansion rate of the universe was measured from distant Type Ia supernovae ‑ cosmic “beacon”, verifying the acceleration of the expanding universe.
Comment from researchers
We developed an ultra-wide-field prime-focus camera called the Hyper Suprime-Cam to investigate the mysterious dark matter and dark energy. Its wide-field of view will allow us to capture interesting objects and strange phenomena that are never been observed nor expected.
