Size comparison of the event horizons of the black holes of TON 618 and Phoenix A. The orbit of Neptune (white oval) is included for comparison. The central black hole of the Phoenix Cluster is the engine that drives both the Seyfert nucleus of Phoenix A, as well as the relativistic jets that produce the inner cavities in the cluster center. M.
Size comparison of the event horizons of the black holes of TON 618 and Phoenix A. The orbit of Neptune (white oval) is included for comparison. As a quasar, TON 618 is believed to be the active galactic nucleus at the center of a galaxy, the engine of which is a supermassive black hole feeding on intensely hot gas and matter in an accretion ...
The supermassive black hole at the core of Messier 87, here shown by an image by the Event Horizon Telescope, is among the black holes in this list.. This is an ordered list of the most massive black holes so far discovered (and probable candidates), measured in units of solar masses (M ☉), approximately 2 × 10 30 kilograms.
Some astronomers refer to black holes of greater than 5 billion M ☉ as ultramassive black holes (UMBHs or UBHs), [19] but the term is not broadly used. Possible examples include the black holes at the cores of TON 618 , NGC 6166 , ESO 444-46 and NGC 4889 , [ 20 ] which are among the most massive black holes known.
This is a list of known black holes that are close to the Solar System. It is thought that most black holes are solitary, but black holes in binary or larger systems are much easier to detect. [1] Solitary black holes can generally only be detected by measuring their gravitational distortion of the light from more

The redshift of J0529-4351 is 3.962. The object itself is classified as a radio-quiet quasar.Fitting accretion models to the spectra yields an accretion rate of matter onto the black hole of 280 to 490 solar masses per year for an accretion disk around the black hole observed at an angle of zero to 60 degrees, with accretion occurring near the Eddington limit.
