Scientists using Space Telescope James Web (JWST) have identified the most black hole found so far, dating back more than 13 billion years ago.
The black hole and its home galaxy, together called capers-LRD-Z9, exist only 500 million years after the Big Bang. Its properties could help researchers understand what the universe is in that elusive early era, according to a study published on August 6 in Astrophysical letters of the magazineS
“When you are looking for Black holesThis is about as far as you can go into practice “Learn co -author Anthony TaylorAstronomer from the University of Texas, Austin, said in a statementS “We really press the limits of what this technology can find.”
Capers-LRD-Z9 is a type of galaxy called A “Red dot“SO NAMED BECAUSE YEY’RE SMALL (AS Galaxies Go) and Appear to EMIT RED LIGHT WHEN OBSERVED with Jwst’s Powerful Infrared Sensors. Little Red Dots Shine Brightly excepted you formed in the early universe, when an abundance of Stars Was Unlikely, Accredit to Current Leading Theories of cosmologyS
“The discovery of small red dots was a big surprise from Jwst’s early data as they did not look like galaxies viewed with the Hubble Space Telescope,” the co -author studied Stephen FinkelsteinUT Austin an astronomer, said in the statement. “Now, we are in the process of inventing how they are and how they appeared.”
To better understand the nature of Capers-LRD-Z9 and small red spots like it, researchers are exploring the galaxy with JWST. The team has found a different model of wavelengths created when the fast moving gas falls into a black hole. Although astronomers have found several objects farther from Capers-LRD-Z9, which may be black holes, this model makes Capers-LRD-Z9 the earliest confirmed black hole to date and suggests that black holes can lie in the center of other small red spots.

The black hole in the center of Capers-LRD-Z9 is quite huge. This is about 38 million times more massive than the sun or about 10 times more massive than Sagittarius A*, An over -massive black hole in the center of the Milky Way – Although there is a significant room in this assessment. Scientists also believe that the black hole has as much mass as about 5% of all stars in its galaxy, assembled together, a ratio far exceeding that of modern galaxies.
“This contributes to the increasing evidence that early black holes have grown much faster than we thought possible,” Finkelstein said. “Or they started far more massive than our models predict.”

Capers-LRD-Z9 can also help explain why small red spots are red. A mold cloud of gas surrounding the black hole can transfer any light emitted to longer, redness of the wave, the researchers predicted.
Further studies on Capers-LRD-Z9 could offer even more information about black holes and galaxies in the early universe, scientists wrote in the study.
“This is a good test object for us,” Taylor said in the statement. “Until recently, we have not been able to study the early evolution of black holes and are excited to see what we can learn from this unique object.”
