Except for the matter at the very center, most of a black hole
is empty space.
The observation result shows that there is a unique chemical composition characterized by enhancement of hydrogen cyanide (HCN) around the black hole
, which would be caused by high temperature heating of the environment surrounding the black hole
Until now all previously known black holes
have been found in multiple star systems, orbiting a companion star.
Another way for a black hole
to grow this big is for it to have gone on a sustained binge, consuming food faster than typically thought possible," said Tsai.
Messier 82, an "intermediate-sized" black hole
, is about 400 times the mass of the sun.
The tiny heavyweight black hole
is in the center of a dwarf disk galaxy, called RGG 118, located about 340 million light years from Earth, and was originally discovered using the Sloan Digital Sky Survey.
These new findings may be a solution to the long debated subject of black holes
or they may just stir up the discussions around it.
A supermassive black hole
is known to be the largest type of black hole
As the test mass was at an arbitrary distance from the origin, this will become equally true for every point within the event horizon of the original black hole
The unified model answers this question by proposing that every black hole
is surrounded by a dusty, doughnut-shaped structure called a torus.
Astronomers have used NASA's Chandra X-ray Observatory and the European Space Agency's (ESA's) XMM-Newton to show a supermassive black hole
six billion light years from Earth is spinning extremely rapidly.
Spin is difficult to measure as it only affects the behaviour of material really close to the black hole
