The James Webb Space Telescope discovered numerous supermassive black holes in the distant universe
The research team led by Yuichi Harikane (Assistant Professor at the Institute for Cosmic Ray Research, the University of Tokyo), including Yechi Zhang (JSPS Fellow) and Kimihiko Nakajima (Project Assistant Professor) at NAOJ, discovered ten supermassive black holes in the distant universe dating back 12 to 13 billion years by using the observational data obtained by the James Webb Space Telescope. This number is 50 times greater than the predictions based on the previous studies, indicating the existence of a large number of supermassive black holes in the distant universe just 1 to 2 billion years after the Big Bang.
