LID-568A supermassive black hole located in early universe only 1.5 billion years belonging big bang, absorbs matter at tremendous speedAccording to an international group of astronomers. This is a phenomenon characterized feed rate is 40 times the theoretical limitchallenges existing theories about the evolution of these celestial bodies.
Supermassive black holes are regions in which the concentration of matter generates a gravitational force so powerful that even light cannot escape its pull. These objects are usually located at the center of galaxies and play an important role in the formation and evolution of galaxies.
The discovery, published this Monday in Nature Astronomywas achieved through advanced infrared surveillance capabilities James Webb Telescope.
The researchers used integrated field spectrograph tool NIRSpec belonging James Webbwhich provides a complete view of both the target and the surrounding area. This approach made it possible to unexpectedly discover powerful gas flows around the central black hole.
The speed and size of these flows led the team to conclude that a significant portion LID-568 weight growth probably happened during a unique and rapid episode of creation.
“He find it would be impossible without this tool James Webb. “This will improve our understanding of black holes and open up interesting avenues of research,” he said. Hyewon SooResearcher at the Gemini International Observatory/NOIRLab USAwho led the work.
LID-568 It is released by devouring matter at a speed of 40 times. superiors
to call Eddington limitwhich determines the maximum luminosity a black hole can achieve and the rate at which it can consume matter.This exceptional behavior became apparent when the researchers calculated that the luminosity LID-568 exceeded what was possible according to modern theories. “Most of the black holes in the early Universe discovered by James Webb are very faint (or undetectable) in X-rays, but LID-569 caught our attention because of its high X-ray brightness.”he explained Mar Mescuafrom the Institute of Space Sciences and the Institute of Space Research of Catalonia (ICE-CSIC, IEEC).
“A fast-feed mechanism above the Eddington limit may be one possible explanation for why we see these heavy black holes so early in the Universe”noted another of the authors, Julia SharvekhterGemini International Observatory/NSF NOIRLab astronomer.
The results provide new insight into how supermassive black holes from smaller “seeds”. Current theories suggest that these seeds may arise from the death of early stars (light seeds) or from the direct collapse of gas clouds (heavy seeds). However, until now there has been no observational data to confirm them.
The discovery of this “Eddington superaccumulator black hole” supports the idea that most of its growth can occur in one quick feeding, regardless of whether it comes from a light or heavy seed, the researcher explained. Su.
Opening LID-568 provides astronomers with an unprecedented opportunity to analyze how black hole may exceed Eddington limitusing detailed observations James Webb Telescope To unravel this phenomenon in early universe.
