    en.wikipedia.org/wiki/Phoenix_Cluster

    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.

  3. TON 618 - Wikipedia

    en.wikipedia.org/wiki/TON_618

    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.

    The universe could be home to far more supermassive black holes than we realised, according to new research. Astronomers from the University of Southampton say that 35% of these galactic giants ...

  7. Supermassive black hole - Wikipedia

    en.wikipedia.org/wiki/Supermassive_black_hole

    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.

    (Supermassive black holes up to 21 billion (2.1 × 10 10) M ☉ have been detected, such as NGC 4889.) [16] Unlike stellar mass black holes, supermassive black holes have comparatively low average densities. (Note that a (non-rotating) black hole is a spherical region in space that surrounds the singularity at its center; it is not the ...
