Scientists have discovered “baby quasars,” black holes that continue to grow

The team of researchers made the discovery with the James Webb Telescope, which allows the first observations of galaxies.

He James Webb Space Telescope (JWST) was discovered A group of faint red dots They could exist in a distant universe Big holes baby, In a discovery that could change the way the origin of these massive objects is understood, as described in a report published by the journal Science. The Astrophysical Journal.

The study was conducted under the leadership of Jorid MethiAn assistant professor of astrophysics at the Austrian Institute of Science and Technology (ISTA), explains that objects of this type existed until the advent of the Webb telescope. “Indistinguishable.”

This telescope A hundred times more sensitive than Hubble With it you can see further into the universe than its predecessors and observe the first galaxies, thanks to the fact that it works in the infrared, which allows you to see. Cold objects that are too far away or obscured by dust.

In his first year, he noticed different things, but maybe these little red spots “Unexpected Development”, Describes the statement.

Although it wasn't built for that purpose, JWST helped us determine “some of the faintest red spots seen in the universe's distant past – Smaller versions of supermassive black holesThis could change the way we understand the origin of black holes,” Methi said.

What are supermassive black holes?

These intriguing peculiarities They have a huge center of gravity that absorbs anything (cosmic dust, planets and stars), in turn They distort space and time around them So even light cannot escape from them.

In his general theory of relativity, Albert Einstein predicted a century ago that black holes could have any mass.

Very unbelievable Supermassive Black Holes (SMBH)Achievable between Millions and billions of times the mass of the sun.

Many astrophysicists agree on that Almost every large galaxy has one of these at its center. At the center of our galaxy Sagittarius A*There is a SMBH Four million times the mass of the Sun And for what it was worth Nobel Prize in Physics 2020.

Not all SMBHs are the same, and Sagittarius A* can be compared to a dormant volcano. Others have enormous powers of growth, as they devour astronomical quantities, which illuminates them so that they can be seen all the way to the edge of the universe. These last They are called quasars and one of the brightest objects in the universe.

That's the problem with causality, Matthi explains “Some of them seem excessively large. Quasars are very large considering the age of the observed universe. “We call them troublesome quasars.”

In the study, experts JWST has identified a number of objects that appear as small red dots in the images And they are not the colossal cosmic monsters found in the most massive SMBHs.

“Troublesome Quasars” blues, Extremely bright and billions of times the mass of the Sun, red spots are like 'baby quasars'. Their mass ranges from ten to a hundred million solar masses. Besides, They appear red because they are covered with dust.hides black holes and reddens colors,” the study explains.

Methi's team believes that, Over time, “the flow of gas from the black holes will pierce the dust core and giants will form from these tiny red dots.”
