CXOU J132527.6-430023 (a candidate stellar mass black hole outside of the Local Group) [ 11] Cygnus X-1. Cygnus X-3. GRO J0422+32 (possibly the smallest black hole yet discovered) [ 12] GRO J1655-40 / V1033 Sco (at one time considered the smallest black hole known) [ 13] GRS 1124-683 / GU Mus. GRS 1915+105 / V1487 Aql.
A black hole with the mass of a car would have a diameter of about 10 −24 m and take a nanosecond to evaporate, during which time it would briefly have a luminosity of more than 200 times that of the Sun. Lower-mass black holes are expected to evaporate even faster; for example, a black hole of mass 1 TeV/c 2 would take less than 10 −88 ...
Like black holes, white holes have properties such as mass, charge, and angular momentum.They attract matter like any other mass, but objects falling towards a white hole would never actually reach the white hole's event horizon (though in the case of the maximally extended Schwarzschild solution, discussed below, the white hole event horizon in the past becomes a black hole event horizon in ...
An accretion disk is a structure (often a circumstellar disk) formed by diffuse material [ a] in orbital motion around a massive central body. The central body is most frequently a star. Friction, uneven irradiance, magnetohydrodynamic effects, and other forces induce instabilities causing orbiting material in the disk to spiral inward toward ...
The matter accreting onto the black hole is unlikely to fall directly in, but will have some angular momentum around the black hole, which will cause the matter to collect into an accretion disc. Quasars may also be ignited or re-ignited when normal galaxies merge and the black hole is infused with a fresh source of matter. [ 48 ]
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 disc.
1 × 1010[ 47] There are actually two black holes, orbiting at each other in a close pair with a 542-day period. The largest one is quoted, while the smaller one's mass is not defined. [ 47] Black hole of central elliptical galaxy of RX J1532.9+3021. 1 × 1010[ 48] QSO B2126-158. 1 × 1010[ 23] – 4.9+1.13.
3C 273 is a quasar located at the center of a giant elliptical galaxy in the constellation of Virgo. It was the first quasar ever to be identified and is the visually brightest quasar in the sky as seen from Earth, with an apparent visual magnitude of 12.9. [ 2]
