Missing a supermassive black hole, NASA says


Astronomers have observed a distant galaxy cluster without the expected supermassive black hole at its center – despite the fact that its mass must be somewhere between three and 100 billion times that of the Sun.

According to a NASA statement, according to observations between 1999 and 2004, the black hole was estimated to be about 2.7 billion light years away from Earth in the galaxy cluster Abell 2261.

More recently, astronomers at the University of West Virginia used NASA’s Lunar X-ray Observatory and the Hubble Space Telescope to eject the region – and could not detect black holes.

Almost every large galaxy in the known universe has a supermassive black hole. The larger the galaxy, the larger the black hole. In fact, this particular black hole was predicted to be the largest on record.

To consider the perspective of a few hundred billion times the mass of the Sun, the central supermassive black hole of the Milky Way is estimated at only four million times the mass of the Sun.

But it is missing. To explain this, scientists have put forward several explanations.

The first is that the black holes could be extracted from its host galaxy as a merger of two galaxies, forming an even more massive galaxy, otherwise called “reclaiming the black hole”.

Alternatively, the corresponding black holes of the two galaxies may merge into a larger supermassive black hole, resulting in a supermassive core at the center of the mega-galaxy. Although this phenomenon is directly implicated in such a black hole, astronomers have associated the merger with a much smaller black hole.

In a paper set to be published in the journal American Astronomical Society, A team led by Sarah Burke-Spoler from the University of West Virginia, put forward two more possible explanations: either there is not just one black hole, or there is actually a black hole that just happens to produce any noticeable quantity Not active enough for. X-ray to show in Chandra comments.

Scientists are hoping to use NASA’s upcoming James Webb Space Telescope to take a closer look.
