Jakarta, CNN Indonesia —
Researchers reveal the reason for the appearance of light from behind black hole. From the observations, light it arises as a result of the release of energy due to gas falling into a black hole.
The incoming gas will release a large amount of energy and spit out electromagnetic radiation in all directions. This makes it the brightest object in the universe.
But these scientists say they can only see light and other radiation from a black hole when it shines directly into the telescope. According to this researcher as well as the theory of general relativity Albert Einstein.
“This is a very exciting result,” said Edward Cackett, an astronomer at Wayne State University citing Technology Review, Thursday (29/7).
“It will also allow for a better mapping of how objects fall into black holes and how black holes bend spacetime around them.”
Quotes Independent, the discovery of light from the other side of the black hole was predicted by Einstein’s theory of general relativity. But that’s never really happened before, and the discovery marks the first time light has ever been observed directly and comes from behind a black hole.
According to other researchers, the release of energy by black holes sometimes comes in the form of x-rays. He said it was a very extreme process.
And because black holes release so much energy, they essentially become the powerhouses that allow galaxies to grow around them.
“If you want to understand how galaxies form, you really need to understand the processes beyond black holes that are capable of releasing this huge amount of energy and power, this incredibly bright source of light that we’re studying,” said Dan Wilkins, an astrophysicist at the University of Chicago. Stanford.
The study focused on the supermassive black hole at the center of a galaxy called I Zwicky 1 (I Zw 1), or about 100 million light-years from Earth.
In a supermassive black hole such as I Zw 1, large amounts of gas fall toward the center and tend to flatten into a disk. Above the black hole, the encounter of supercharged particles and magnetic field activity results in the production of high-energy x-rays.
Some of these x-rays shine through and we can observe them normally, using a telescope. But some of them also shine toward the flat disk of gas and will reflect it.
Then the rotation of the I Zw 1 black hole slows down at a rate higher than that seen in most supermassive black holes and it causes the gas and dust around it to fall more easily and ‘feed’ the black hole from various directions. This, in turn, results in greater x-ray emission.
