In the case of S5 0014+81, it is one of the most luminous quasars known, with a total luminosity of over 10 41 watts, [2] equal to an absolute bolometric magnitude of −31.5. If the quasar were at a distance of 280 light-years from Earth , it would give out as much energy per square meter as the Sun does at Earth, despite being 18 million ...
S5 0014+81: 4 × 10 10 [26] [27] [28] A 2010 paper suggested that a funnel collimates the radiation around the jet axis, creating an optical illusion of very high brightness, and thus a possible overestimation of the black hole mass. [26] NGC 3842: 3.46 +6.30 −2.24 × 10 10 [15] [16] Brightest galaxy in the Leo Cluster; estimation using break ...
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.
Markarian 501 and S5 0014+81 are also called "TeV Blazars" for their high energy (teraelectron-volt range) gamma-ray emission. In July 2018, a blazar called TXS 0506+056 [ 12 ] was identified as source of high-energy neutrinos by the IceCube project.
In addition, Cepheus also has the hyperluminous quasar S5 0014+81, which hosts an ultramassive black hole in its core, reported at 40 billion solar masses, about 10,000 times more massive than the central black hole of the Milky Way, making this among the most massive black holes currently known. [2] [3]
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.
Abell 1201 BCG (short for Abell 1201 Brightest Cluster Galaxy) is a type-cD massive elliptical galaxy residing as the brightest cluster galaxy (BCG) of the Abell 1201 galaxy cluster. [3]
IC 1101 is a class S0 supergiant lenticular galaxy at the center of the Abell 2029 galaxy cluster.It has an isophotal diameter at about 123.65 to 169.61 kiloparsecs (400,000 to 550,000 light-years).
