SMSS J215728.21-360215.1, commonly known as J2157-3602, is one of the fastest growing black holes and one of the most powerful quasars known to exist as of 2021.The quasar is located at redshift 4.75, [1] corresponding to a comoving distance of 2.5 × 10 10 ly from Earth and to a light-travel distance of 1.25 × 10 10 ly.
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.
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.
At the heart of our Milky Way galaxy lurks a supermassive black hole about four million times the mass of the sun, called Sagittarius A*. But since NASA's James Webb Space Telescope came online in ...
NASA has identified a rapidly growing black hole that was long considered a critical "missing link" to the early universe. Dr. Jennifer Wiseman, a senior astrophysicist at the NASA Goddard Space ...
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.
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]
Another study from June of 2023 reported an X-ray echo that pointed to the idea that the Milky Way’s black hole, Sagittarius A* (Sgr A*), had experienced its own flare up some 200 years ago.
