A tremendous Black hole Slips out of the astronomers’ lattice.
Supermassive black holes are thought to be hidden in the hearts of most people, if not galaxies. Our own galaxy contains one as large as 4 million suns, for example, and M87’s – The Only black holes image directly – Total 6. 2. Billion solar masses give tips to the scales.
The large galaxy on the main side of the cluster Abel 2261, which is about ૨ from Earth. Billion billion light-years, it must have had a much larger central black hole – a light-gobling monster weighing from a billion to 100 billion, astronomers estimate the mass of the galaxy but the foreign object object has so far gone undetected.

For example, researchers previously discovered X-ray streaming from the center of the galaxy, using data collected by NASA. Lunar X-ray Observatory In 1999 and 2004. X-rays are potentially black-hole signatures: As the material enters the black hole’s mass, it accelerates and heats up tremendously, emitting a lot of high-energy X-ray light. But that hunt is nothing.
Now, in a new study in the same galaxy, a more erratic search for X-rays has been conducted, using lunar observations from 2018 onwards. And this new effort doesn’t just appear at the center of the galaxy; Also consider the possibility that the black hole was knocked out to the hinterland after a monster Galactic merger.
When black holes and other large objects collide, they emit ripples called space. Gravitational waves. If the emitted waves are not symmetrical in all directions, they could propel a merged supermassive black hole away from the center of the newly expanded galaxy, scientists say.
Such “reclining” black holes are perfectly predictable creatures; No one has definitely spotted it to date. Indeed, “it is not known whether supermassive black holes also come close enough to each other to produce and merge gravitational waves; so far, astronomers have only tested the merger of many small black holes,” NASA officials wrote in a letter. Statement about the new study.
They added that the investigation into the control of supermassive black holes would encourage scientists to detect gravitational waves by merging into supermassive black holes and to develop observatories.
The central galaxy of Abel 2261 is a good place to hunt such unicorns, the researchers said, adding that it has many potential signs of a dramatic merger. For example, observations by Hubble Space Telescope And the ground-based Subaru Telescope shows that its main, highest stellar density field Much bigger than expected For a galaxy of its size. About 2,000 light-years away from the center of the galaxy is a patch of galaxies, NASA officials wrote.
In a new study, a team led by Kehan Gultekin of the University of Michigan found that the concentration of hot gas is not in the central regions of the galaxy. But lunar data did not reveal any significant X-ray sources, either in the core of the galaxy or ahead of most of the stars. So the mystery of the missing supermassive black hole remains.
That mystery can be solved by Hubble’s successor – NASA’s big, powerful James Webb Web Space Telescope, Which is scheduled to start in October 2021.
If James Webb could not find a black hole in the heart of the galaxy or in the clusters of its large stars, “the best explanation is that the black hole has protruded beyond the center of the galaxy,” NASA officials wrote.
A new study has been approved for publication in the Journal of the American Astronomical Society. You can read it for free on the prep online print site arXiv.org.
