A supermassive black hole spins more slowly than a less massive black hole.


A supermassive black hole spins more slowly than a less massive black hole.

About 3.4 billion light-years from Earth is the H1821+643 quasar, a quasar powered by a supernova black hole, a quasar also known as a quasi-stellar object, and an extremely luminous active galactic nucleus (AGN). Happens. The mass of a quasar ranges from millions to billions, and its solar mass is surrounded by a gaseous accretion disk, a gaseous accretion disk caused by the force of gravity, the gas due to friction in the disk falling toward the black hole. It heats up, releasing energy in the form of electromagnetic radiation. Researchers believe that the radiant energy of a quasar is very large, and the most powerful quasar shines thousands of times brighter than the Milky Way.

The actively growing black hole in the H1821+643 quasar has a solar mass of about three to 30 billion, and the supermassive black hole at the center of the Milky Way weighs about four million Suns. The researchers used Chandra X-ray and Jansky Very Large Array data for a combined image of H 1821+643, combined with an optical image from the PanSTARRS telescope, and the researchers used Chandra X-ray to get this latest result. Observed data taken over a decade ago by the X-ray Observatory.

A swirling black hole attracts all objects that come close to it contains a supermassive black hole, the accretion of interstellar gas that accelerates active galactic nuclei and quasars. The supermassive black hole is located in the bright point at the center of X-ray emission, X-ray data showing how fast the black hole is spinning, H1821+643 indicates the amount of energy as a function wavelength, That’s how black holes are spinning at a marginal rate compared to others, but massive black holes move at close to the speed of light.

Researchers say that the black holes in H1821+432 are only rotating half as fast as their lower-mass cousins, why is that? He answers this, that how black holes grow and develop depends on it. The relatively slow spin suggests to researchers that the largest black holes, such as H1821+643, when merged with other smaller black holes, are pulled inward by the gas in random directions, forming a larger disk. Often such a supermassive black hole is likely to have a large variation of spin, in which the black hole starts spinning slowly, sometimes in the opposite direction. The researcher says that we should see the largest black holes as having a wider range of spin rates than the less massive blacks.

Researchers, on the other hand, expect that black holes smaller than supermassive black holes store most of their mass in the form of a disk of gas revolving around them, and the researchers expect such a disk to be stable. The black hole will continue to spin until its speed reaches the speed of light.
