illustration shows the bright active region of the quasar J1120+0641 with a supermassive black hole in an"ultra-effective feeding mode"Using the James Webb Space Telescope , astronomers have spotted a supermassive black hole at"cosmic dawn" that seems to be impossibly massive.
"Overall, the new observations only add to the mystery: Early quasars were shockingly normal," team leader and Max Planck Institute for Astronomy post-doctoral researcher Sarah BosmanBreaking space news, the latest updates on rocket launches, skywatching events and more!Receive email from us on behalf of our trusted partners or sponsors
Because of the conservation of angular momentum, matter can't fall directly into a black hole. Instead, a flattened cloud of matter called anis formed around the black hole. Further, the immense gravity of the central black hole gives rise to powerful tidal forces that create turbulent conditions in the accretion disk, heating it and causing it to emit light across the electromagnetic spectrum.
MIRI observations of this quasar showed that the cosmic supply chain functions similarly to that of"modern" quasars closer to Earth that therefore exist in later epochs of the universe. That's bad news for proponents of the theory that an enhanced feeding mechanism led to the quick growth of early black holes. The JWST observations of this quasar did reveal one major difference between it and its modern counterparts.
