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.
Masses of black holes in quasars can be estimated via indirect methods that are subject to substantial uncertainty. The quasar TON 618 is an example of an object with an extremely large black hole, estimated at 4.07 × 10 10 (40.7 billion) M ☉. [108] Its redshift is 2.219.
Ton 618: 1.3 × 10 41 kg: 1.9 × 10 14 ... [note 3] Its average density at that size would be so high that no known mechanism could form such extremely compact objects.
The Phoenix Cluster (SPT-CL J2344-4243) is a massive, Abell class type I galaxy cluster located at its namesake, southern constellation of Phoenix.It was initially detected in 2010 during a 2,500 square degree survey of the southern sky using the Sunyaev–Zeldovich effect by the South Pole Telescope collaboration.

These are objects without a host galactic group, caused by collisions between two galaxies or when the merging of two black holes is disrupted. It has been estimated that there could be 12 rogue supermassive black holes on the edge of the Milky Way galaxy.

I read your article S50014+81 and believe it is the largest.But when I read about TON618 Iwas amazed that so large! AY87 16:06, 21 November 2017 (UTC) [] WOW🥹 2601:5CA:C280:64B0:F466:C898:AC44:9621 00:21, 11 June 2024 (UTC) []
