A new groundbreaking discovery by scientists from Ehime University and the National Astronomical Observatory of Japan (NAOJ) has revealed supermassive black holes shrouded in dust in the early universe that had previously escaped detection. Using a combination of the Subaru Telescope and the James Webb Space Telescope (JWST), the team identified these hidden quasars, showing that bright quasars were at least twice as common in the cosmic dawn than previously thought.

This study significantly expands our understanding of how supermassive black holes form and evolve, offering new perspectives on galaxy formation and the universe's structure. The research highlights the effectiveness of combining the Subaru's wide-field observations with the JWST's infrared capabilities to overcome the limitations of conventional surveys that rely on ultraviolet light, which is easily absorbed by dust. With plans for future observations and detailed analysis, this team is poised to continue unraveling the mysteries of the cosmic dawn and deepen our knowledge of supermassive black holes.
