What is Intermediate-Mass Black Hole? Hubble Space Telescope helps astronomers discover it. Details here

Big black holes, which can have masses up to hundreds of thousands of times that of the sun, are less common than small black holes, which are often found between five and 100 times that of the sun. There are still unanswered concerns regarding the genesis and growth of black holes due to the elusiveness of intermediate-mass black holes (IMBH). Intermediate-mass black holes should be more prevalent if they form gradually from smaller ones. In contrast, it would contradict what we know about black hole physics if they are limited to tiny or gigantic sizes, as per the reports of MSN.

Seeking for black holes with intermediate mass

Astronomers have been searching for these IMBHs for a long time. Some of the greatest evidence for an IMBH in the Milky Way, notably in the Omega Centauri cluster, has just been revealed by the Hubble Space Telescope. About 10 million stars reside in Omega Centauri, and Hubble has played a crucial role in the cataloging of these stars.

Findings in Omega Centauri

An anomaly was discovered by researchers while cataloging. "We found seven stars that shouldn't be there," Max Planck Institute for Astronomy lead researcher Maximilian Haberle remarked. These stars were traveling so quickly that they ought to break free of the cluster completely. The most likely scenario is that these stars are being pulled toward the center of the galaxy by a large object.

Evidence of an Intermediate-Mass Black Hole

Strong gravitational pulls can only be produced by black holes, which have masses estimated to be at least 8,200 times that of the sun. This categorizes the item firmly inside the IMBH group. Although earlier research suggested that there might be an IMBH in Omega Centauri, this new data is the strongest to date. It implies the existence of a close-by IMBH, which may be essential for researching the evolution of black holes.

Future research

As per the reports of MSN, the James Webb Space Telescope will now be used by researchers to study this black hole in more detail. With the use of this cutting-edge telescope, it will be possible to pinpoint the IMBH's precise mass and location, shedding light on both its characteristics and the larger processes behind black hole formation.

The findings have been published in the journal Nature.

FAQs:

What are the sizes of black holes usually found?
Astronomers typically find small black holes, 5-100 times the mass of the sun, and supermassive black holes, hundreds of thousands of times the sun's mass.

What is an intermediate-mass black hole (IMBH)?
An IMBH is a black hole with a mass between small and supermassive black holes, typically several thousand times the mass of the sun.
