Science Results - Astronomers Discover 83 Supermassive Black Holes in the Early Universe Yoshiki Matsuoka

A team of astronomers has discovered 83 quasars powered by supermassive black holes (SMBHs) in the distant universe, from an epoch when the universe was less than 10 percent of its present age. This finding was made by using the wide-field camera Hyper Suprime-Cam (HSC) mounted on the Subaru Telescope. The discovery increases the number of black holes known at that epoch considerably, and reveals, for the first time, how common SMBHs are early in the universe’s history. In addition, it provides new insight into the effect of black holes on the physical state of gas in the early universe in its first billion years.
