Researchers have experimentally confirmed the rotation of a supermassive black hole.
A supermassive black hole in the galaxy M87 is showing an oscillating jet burst, confirming its rotation, according to a twenty-year study that fully matches predictions based on Einstein's general theory of relativity.
The study, led by Chinese scientist Dr Yuzhu Cui and published in the journal Nature on September 27, was carried out by an international team using a global network of radio telescopes. Analysis of data from 2000 to 2022 showed that the rotation of the black hole actually occurs, which was revealed by observing the 11-year cycle of precessional motion of the base of the jet ejection.
The phenomenon of supermassive black holes
Supermassive black holes at the center of active galaxies are extremely powerful and can accumulate a huge amount of matter. The energy exchange between black holes, their accretion disks, and jet ejections has been a subject of debate for more than a century. This study was carried out at the supermassive black hole M87, where an astrophysical jet burst was first recorded in 1918.
Black hole dynamics and relativity
The main question at the center of this discovery is what forces can change the direction of such a powerful jet blast. The answer may lie in the behavior of the accretion disk associated with the central supermassive black hole, which affects the surrounding space, causing nearby objects to move along its axis of rotation. This phenomenon was predicted by Einstein's General Theory of Relativity.
Research value and future prospects
A team of researchers conducted a thorough analysis that indicates that the black hole in M87 is indeed rotating, thereby deepening our understanding of the nature of supermassive black holes.
"We are thrilled with this important finding," said Dr Yuzhu Cui of the Zhejiang Lab. Dr Kazuhiro Hada, from the National Astronomical Observatory of Japan, added that now " expectation has turned into confidence. This monstrous black hole is really spinning."
More than 20 telescopes around the world contributed to this study, including the Tianma Telescope in China. So far, the structure of the accretion disk and the exact value of the rotation of the supermassive black hole M87 remain the subject of debate, but this work predicts the presence of more such configurations, posing new challenges for scientists.
Conclusion
The study reveals the secrets of supermassive black holes and poses new challenges for the scientific community, waiting for discoveries and refinements in this exciting field of astrophysics.
