Article states width of 7 ly pertaining to the accretion disk of this monster -- 45,000 AU equivalence seems to be a typo. May be that a zero was dropped. My (possibly incorrect) quick calc gives ...

"A quasar accretion disc has a typical size of a few light-days, or around 100 billion kilometres across, but they lie billions of light-years away.

The team saw, for the first time, near-infrared emission lines in the spectrum of light coming from this quasar's accretion disk. Those lines helped the researchers size this plate-like structure ...

New research suggests that galaxies with quasars at their active hearts are seven times more likely to harbor elusive supermassive black hole binary paintings than other galaxies.

This may be an observation of the quasar's active accretion disk. Event Horizon Telescope collaboration, ApJ 875, 1 (2019) What we're seeing, for the very first time, is the accretion disk around ...

“If it wasn’t removed, angular momentum would actually completely stop the accretion and turn off the quasar,” says Young, a post-doctoral fellow at RIT, formerly of the University of Hertfordshire, ...

The light from a quasar is produced by an accretion disk. While accretion disks can form around black holes with masses similar to stars, quasars require a supermassive black hole like the ones ...

But when that accretion rate drops, the disk puffs up into a quasi-spherical structure that struggles to emit light. A changing-look quasar goes from bright (left/top) to dim in just a few years ...

“A quasar accretion disk has a typical size of a few light-days, or around 62 billion miles (100 billion kilometers) across, but they lie billions of light-years away,” said Jose Muñoz from ...
