The emission lines in the spectrum of TON 618 have been found to be unusually wide, [7] indicating that the gas is travelling very fast; the full width half maxima of TON 618 has been the largest of the 29 quasars, with hints of 10,500 km/s speeds of infalling material by a direct measure of the H β spectral line, indication of a very strong ...
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.
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 Schwarzschild radius or the gravitational radius is a physical parameter in the Schwarzschild solution to Einstein's field equations that corresponds to the radius defining the event horizon of a Schwarzschild black hole.
Animation of a Lyman-alpha blob. The giant Lyman-alpha blob LAB-1 (left) and an artist's impression of what it might look like if viewed from relatively close (right).. In astronomy, a Lyman-alpha blob (LAB) is a huge concentration of a gas emitting the Lyman-alpha emission line.
Globular cluster Mayall II (M31 G1) is a possible candidate for hosting an intermediate-mass black hole at its center [1]. An intermediate-mass black hole (IMBH) is a class of black hole with mass in the range of one hundred to one hundred thousand (10 2 –10 5) solar masses: significantly higher than stellar black holes but lower than the hundred thousand to more than one billion (10 5 –10 ...
tech: approximate range of peak power output of typical automobiles (50-250 hp) 5–10 × 10 4 W tech: highest allowed ERP for an FM band radio station in the United States [27] 10 5: 1.67 × 10 5 W tech: power consumption of UNIVAC 1 computer 2.5–8 × 10 5 W tech: approximate range of power output of 'supercars' (300 to 1000 hp) 4.5 × 10 5 W
In physics, black hole thermodynamics [1] is the area of study that seeks to reconcile the laws of thermodynamics with the existence of black hole event horizons.As the study of the statistical mechanics of black-body radiation led to the development of the theory of quantum mechanics, the effort to understand the statistical mechanics of black holes has had a deep impact upon the ...
