The H1821 + 643 is a quasar powered by a large black hole, located about 3.4 billion light-years from Earth. Astronomers used NASA’s Chandra X-ray Observatory to determine the rotation of the black hole at H1821 + 643, making it the largest to have an accurate measurement of this base, as described in our press statement. Astronomers estimate that the active black hole in the H1821 + 643 contains between 3 and 30 billion solar cells, making it one of the largest known. In contrast, the huge black hole in the center of the Milky Way galaxy has a mass of about four million days.
This H1821 + 643 composite image contains X-rays from Chandra (blue) combined with radio data from NSF’s Karl G. Jansky Very Large Array (red) and a visual image from PanSTARRS in Hawaii (white) and yellow). Researchers have used Chandra’s week-long watch, taken over the past two decades, to find the latest result. A large black hole is found in a bright spot in the center of the radio and X-ray emission.
Because the rotating black hole takes up space through it and allows the object to rotate closer to it than is likely to turn, X-ray data can show how quickly the black hole rotates. The spectrum – that is, the amount of energy as a working wavelength – of H1821 + 643 indicates that the black hole rotates in a relatively small amount compared to the other, smaller ones that rotate closer to the speed of light. This is the most accurate measure of a large black hole cast.
Why is the black hole in H1821 + 432 spinning only about half at the speed of the low cousin price? The answer may depend on how well these large black holes grow and change. This slow spin supports the notion that larger black holes like the H1821 + 643 grow larger in combination with other black holes, or that gas is drawn in random ways when its large discs are disturbed.
Large black holes growing in these ways are likely to experience major spin changes, including shortening or choking on the other side. The prediction is therefore that very large black holes should be considered to have a wider range of rotation rates than their smaller relatives. Scientists, on the other hand, expect small black holes to accumulate a large portion of their weight from a gas spinning disk. around them. Because such disks are expected to stabilize, the incoming material is constantly moving away from the side which will cause the black holes to rotate as fast as possible at the highest possible speed, which is the speed of light.
