TON 618 (abbreviation of Tonantzintla 618) is a hyperluminous, broad-absorption-line, radio-loud quasar, and Lyman-alpha blob [2] located near the border of the constellations Canes Venatici and Coma Berenices, with the projected comoving distance of approximately 18.2 billion light-years from Earth.
The Whirlpool Galaxy is a spiral galaxy tilted face-on to observers on Earth, and was the first galaxy whose spiral nature was discerned. In addition, quasar TON 618 is one of the most massive black holes with the mass of 66 billion solar masses.
Ton 618 (this quasar has possibly the biggest black hole ever found, estimated at 66 billion solar masses) [1] 3C 371; 4C +37.11 (this radio galaxy is believed to have binary supermassive black holes) [2] AP Lib; S5 0014+81 (said to be a compact hyperluminous quasar, estimated at 40 billion solar masses) [3]
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: TON 618 is a very distant and extremely luminous quasar—technically, a hyperluminous, broad-absorption line, radio-loud quasar—located near the North Galactic Pole in the constellation Canes Venatici.
