This time, scientists from the Max Planck Institute used the James Webb Space Telescope to study ancient galaxies with them.

Quasars are unusual forms of supermassive black holes. They absorb matter with such force and speed that their immediate surroundings become extremely bright, outshining even the light of their own galaxy. However, researchers are not only interested in quasars, but also in the galaxies mentioned above.

the nature-in According to a published publication, scientists from the Max Planck Institute for Astronomy have observed two quasars: J2236 + 0032 and J2255 + 0251. These are not the brightest objects in the early universe, which is good, because it was possible to measure the light of surrounding galaxies with the help of the James Webb Space Telescope. .

Their light comes from a time when the universe was only 870-880 million years old.

According to Knud Janke, a faculty member at the institute, nearly 25 years ago we could only see 3 billion light-years away, then Hubble came along, and it became possible to look back 10 billion years. And now, with the help of James Webb, we can see even further, where the first supermassive black holes appeared – he summed up his words IFLScience.

With the help of light, they estimated the mass of the galaxies, which is between 130 and 34 billion times the mass of the Sun. Its supermassive black holes have masses of 1.4 billion and 200 million solar masses, respectively. By comparison, the Milky Way is nearly twice as massive as the smaller quasar, while the supermassive black hole at its center, Sagittarius A*, is four million times the mass of the Sun.

Despite the differences, the mass of stars and the mass of a supermassive black hole exhibit a ratio similar to what we see in the current state of the universe. We don’t know what the connection is: supermassive black holes and stellar populations may have arisen from the same processes, but it’s also possible that they actually influence each other’s evolution.

The fact that this relationship can already be observed in the early universe raises some questions. For example, what made these objects so big in such a short time, and whether the same relationship could exist even if we looked further out into the universe.

In the future, the researchers want to monitor 10 more analogues to get closer to answering these questions.
