ULAS J1342+0928 is the third-most distant known quasar detected and contains the second-most distant and oldest known supermassive black hole, [1] [5] [6] [7] at a reported redshift of z = 7.54. The ULAS J1342+0928 quasar is located in the Boötes constellation . [ 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.
QSO J0313−1806 [2] was the most distant, and hence also the oldest known quasar at z = 7.64, at the time of its discovery. [1] In January 2021, it was identified as the most redshifted (highest z) known quasar, with the oldest known supermassive black hole (SMBH) at (1.6 ± 0.4) × 10 9 solar masses.
It challenged a previously held scientific consensus on gamma-ray burst progenitors [1] and black holes. [ 2 ] Prior to this detection, it was believed that a long gamma-ray burst, like GRB 060614, was probably caused by gravitational collapse of a large star into a black hole, and would be accompanied by detectable supernova , whilst short ...
The telescopes used the light from a much closer cluster of galaxies, a mere 3.2 billion light-years from Earth, to magnify UHZ1 and its black hole much farther in the background.
1972 — Jacob Bekenstein suggests that black holes have an entropy proportional to their surface area due to information loss effects; 1974 — Stephen Hawking applies quantum field theory to black hole spacetimes and shows that black holes will radiate particles with a black-body spectrum which can cause black hole evaporation
Astronomers say they have discovered the longest pair of black hole jets ever seen in the sky coming from a galaxy far, far away. The record-breaking eruptions span 23 million light years from end ...
The Event Horizon Telescope (EHT) is a telescope array consisting of a global network of radio telescopes.The EHT project combines data from several very-long-baseline interferometry (VLBI) stations around Earth, which form a combined array with an angular resolution sufficient to observe objects the size of a supermassive black hole's event horizon.
