NASA has discovered a rapidly growing black hole. This is the “missing link” that connects the origins of the universe hidden in the clear view.

That’s a question that has plagued astronomers for years: how Supermassive black holeIt can weigh billions of times the mass of the sun, but is it very large and grows very fast? Now scientists are closer to the answer than ever before.

Announced by NASA Last week, a potential “missing link” between the universe’s first supermassive black hole and a young star-forming galaxy was hidden in clear view-and it reveals some of the mysteries of how the universe was formed. Helps to explain.

Using data from the Hubble Space Telescope, astronomers have discovered a fast-growing black hole called the GNz7q. Scientists say it “lurks unnoticed” in one of the most well-studied areas of the sky, the Great Observatories Origins DeepSurvey-North field.

Use of archived data from HubbleThe Advanced Camera for Surveys, a team of international researchers, had a “monster” object just 750 million years after the Big Bang, during the early “dawn of the universe” after the birth of the universe. I decided. It is the first of its kind to be discovered.

An international team of astronomers have discovered a unique object in the distant universe, an important link between young star-forming galaxies and the earliest supermassive black holes. This object, called GNz7q, is a deep survey of the origin of the Hubble Space Telescope-the red dot in the center of the northern image.

Scientists have discovered compact UV and infrared light sources that are not solely due to star formation. Rather, it matches the radiation expected by the material falling into the black hole.They say that the best explanation is a dust-covered, fast-growing black hole, which ultimately quasarA brilliant light source in the center of the baby galaxy.

This type of black hole, which turns into a very bright quasar, was predicted by theory and computer simulation, but has never been observed before.The survey results are Release In Journal Nature.

“According to our analysis, GNz7q is the first example of a rapidly growing black hole in the dusty core of a starburst galaxy in an era near the earliest supermassive black holes known in the universe.” The lead author, Seiji Fujimoto, said. “The properties of the object over the entire electromagnetic spectrum are in very good agreement with the predictions from theoretical simulations.”

“GNz7q provides a direct connection between these two rare populations and provides a new way to understand the rapid growth of supermassive black holes in the early universe,” continued Fujimoto. .. “Our findings provide an example of the precursors to supermassive black holes observed in later times.”

Other interpretations of the data are possible, but scientists state that the observations are in strong agreement with previous theories. They were surprised to find a monumental discovery in a place that could be considered a more obvious place. This suggests the possibility of more similar objects.

“GNz7q is a unique discovery found in the middle of a well-studied and famous skyfield, showing that big discoveries are often hidden in front of us,” said team member Gabriel Brammer. Says. “It is unlikely that the discovery of GNz7q within the relatively small GOODS-North study area was simply” unlucky “, but the prevalence of such sources is actually higher than previously thought. It can be significantly higher. “

Next, the team plans to use a dedicated survey to find related objects.Researchers also use the newly launched one James Webb Space TelescopeA spectroscopic instrument for further study of GNz7q — and understand how common these types of objects are.
