Astronomers discover the oldest black hole ever

Identify an international team of astronomers The oldest black hole everAn old giant was present only 500 million years after the Big Bang. The discovery can provide new evidence for a mysterious category of ancient galaxies that confuse the theories of prevailing cosmology.

In a new paper published in Astronomical physical magazine messagesCapers-LRD-Z9-a galaxy far from gas with a The superior black hole In its center. It dates back to about 13.3 billion years, a point where the universe was only 3 % of its current age. Capers-LRRD-Z9, which was detected by James Webb Space Telescope, is one of the many “small red point” galaxies-these strange bodies began to appear in the web images during the first year of the telescope mission.

“The discovery of the Dots Little Red Dots was a big surprise from the early JWST data, as it did not seem like the galaxies that were seen with the Hubble Space Telescope,” said Stephen Venkelstein, co -author of the new study and director of the Cosmic Border Center at the University of Texas in Austin. “Now, we are in the process of knowing what looks like them and how they have become.”

Little galaxies red It was named by its brochure in Webb’s pictures, and there was no telescope before the Webb of sensitivity or accuracy to detect such Distant creatures– Thus, why no one has seen them before. They discovered the ideas of consensus about our world as a question: If these things are stars, strong light emissions mean that some galaxies have grown so large and fast that the prevailing theory cannot be interpreted, according to what they mentioned. Nassa.

Venkelstein and his colleagues One of the largest samples of the Red Point Litte has been assembled so farAlmost all of them were present during the first 1.5 billion years after the big explosion. This study, published in January, found that a large number of these creatures most likely contained increasing black holes. The result provided an alternative explanation for the extent of the light from which galaxies emitted, but they need more evidence to support their theory.

So Vinklstein and a team led by Anthony Taylor, post-doctoral researcher at the Cosmic Border Center who also worked in the research published in January, through spectroscopy data from the Webb’s Capers (Candels-Erea Prism Epoch of Reconization Program). Specger analysis measures different wavelengths of light to detect details about the properties of the object.

when Black holes It interacts with the surrounding gas clouds, and it produces a distinctive fraudulent signature: the gas rotates quickly around it and falls into a black hole, and the light from the gas that moves away from the United States is extended to red wavelengths, while the light from the gas that moves towards the United States bends to the Bluer wavelengths.

“There are not many other things that create this signature,” said Taylor, and Capers-LRD-Z9. This discovery represents the first time that astronomers find this spectral signature associated with a small red galaxy, according to the team, indicating that the super black holes are the potential source of their unjustified brightness. Work can also help explain what these galaxies are red: if the light passes through a thick cloud of gas around the super black hole, it will extend to wavelengths held.

“We have seen these clouds in other galaxies,” Taylor said. “When we compared this object with these other sources, that was a dead Ranger.”

The discovery can also provide new visions in the development of the black hole. Taylor and his colleagues estimate that the black hole in the middle of this galaxy is enormous – to between 300 million times of the sun. Venkelstein said that finding a black hole of this size was very early in the universe “adding to increasing evidence that early black holes have grown much faster than we thought.” “Or they started more huge than our models predicted.”
