Scientists using James Webb Space Telescope (JWST) found the earliest black hole found so far dated more than 13 billion years ago.
The black hole and her home galaxy, along with the Capers-LRD-Z9, existed just 500 million years after the Great Bang. According to the study published on August 6, a study published on August 6 Letters of astrophysical magazines;
“In search of Black holesThis is about as much as you can practically go, ”study co -authors Anthony TaylorThe Astronom, Austin of Texas University, said a a statement; “We really go beyond what the current technology can determine.”
Capers-LRD-Z9 is a type of galaxy called a ‘A small red dot“So named because they are small (as galaxies go) and seem to emit red light when observed with powerful JWST infrared sensors. Small red dots shine bright, which may think they may have many stars – unless Cosmology;
“The discovery of small red dots was the main surprise from the early JWST data as they did not seem like the galaxy seen with the Hablo Space Telescope,” the co -author of the study co -author Steven FinkelsteinThe statement said UT Austin’s astronomer. “Now we find out what they are and how they came.”
To better understand the nature of the Capers-LRD-Z9 and similar to small red dots, researchers studied the galaxy with JWST. The team found a clear light wavelength pattern designed for fast moving gas fall into the black hole. Although astronomers have found several objects further than the Capers-LRD-Z9, which may be black holes, this model makes the Capers-LRD-Z9 earliest to date black hole and indicate that black holes may be in the center of other small red dots.

The black hole in the Capers-LRD-Z9 center is quite heavy. This is about 38 million times more massive than the sun or about 10 times more massive than Sagittarius A* Supermassive black hole in the center of the Milky Way – Although there is a lot of excitement during that estimate. Scientists also believe that the black hole has as much mass as about 5% of all its galaxies stars that are connected and the ratio is significantly higher than modern galaxies.
“This further increases the evidence that early black holes have grown much faster than we thought possible,” Finkelstein said. “Or they started much more massive than our models predict.”

The Capers-LRD-Z9 could also help you explain why small red dots are red. Researchers predicted that the dense gas cloud, surrounding the black hole, could lift any light emitted to longer, reder wavelengths.
Further research on the Capers-LRD-Z9 could offer even more information about black holes and galaxies in the early universe, the research wrote.
“This is a good test object for us,” Taylor said in a statement. “We have recently been unable to study the early black hole evolution and are glad to see what we can learn from this unique object.”
