First detection of an overmassive black hole galaxy UHZ1: evidence for heavy black hole seed formation from direct collapse
The recent Chandra-JWST discovery of a quasar in the z≈ 10.1 galaxy UHZ1 reveals that
accreting supermassive black holes were already in place 470 million years after the Big …
