U.S. astronomers have detected intermittent flickering from a distant quasar dating to the cosmic dawn, about 850 million years after the Big Bang — the earliest such flicker observed. Brightness variations indicate the central supermassive black hole is surrounded by a geometrically thin, optically thick accretion disk: a flattened but very dense, radiation-trapping disk.

U.S. astronomers have detected intermittent flickering from a distant quasar dating to the cosmic dawn, about 850 million years after the Big Bang — the earliest such flicker observed. Brightness variations indicate the central supermassive black hole is surrounded by a geometrically thin, optically thick accretion disk: a flattened but very dense, radiation-trapping disk. Researchers report the thin-disk configuration persists even when accretion rates approach the theoretical maximum, a finding that informs models of early supermassive black hole growth.
