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.
OJ 287 core black holes — a BL Lac object with a candidate binary supermassive black hole core system [23] PG 1302-102 – the first binary-cored quasar — a pair of supermassive black holes at the core of this quasar [24] [25] SDSS J120136.02+300305.5 core black holes — a pair of supermassive black holes at the centre of this galaxy [26]
A look at the mysteries of black holes and theories about the existence of other kinds of holes, such as "mini" or microscopic black holes that exist at the atomic level; "white holes"—the opposite of black holes where matter is ejected out; and "wormholes"—gateways in hyperspace that connect points in space and time and possibly lead to ...
The science and philosophy channel Kurzgesagt has come out with a mind-blowing size comparison of the universe's black holes. The post Black Hole Size Comparison Chart Gives New View of Universe ...
In addition, Abell 85 has its velocity dispersion of dark matter halo at ~750 km/s, which could be explained only by a black hole with a mass greater than 150 billion M ☉, although Kormendy and Ho et al stated that "dark matter halos are scale-free, and the SMBH-dark matter coevolution is independent from the effects of baryons". [2]
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.
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 disc.
