Scientists have discovered the most distant quasar with powerful radiation

Researchers at the European Southern Observatory said they have found the most distant source of radio emission. It is 13 billion light years away.

In a study published in the scientific publication The Astrophysical Journal, the researchers described a quasar located at a very distant distance from Earth – 13 billion light years. In this case, the object emits a very powerful radiation flux in the radio range. Therefore, the light from it went to us for about 13 billion years, and the device of the European Southern Observatory (VLT ESO) recorded it when the age of the universe was only 780 million years.

The scientists explained that quasars are bright objects that can sometimes be seen in the center of some galaxies. According to the latest data, these are active galactic nuclei at the initial stage of development, in which a supermassive black hole absorbs the surrounding matter.

It is this quasar that holds the record because of the cosmic jet, which propagates perpendicular to the accretion disk. It is only about 1000 years old. Space jets are ultra-high-speed material that bursts out of the center of the galaxy, and when interacting with galactic gas, they eject a huge amount of energy in the form of radio waves.

“They play an important role in regulating the formation of stars and the growth of host galaxies, so this discovery is very important for understanding these processes in the early universe,” – said Chris Carilli, astronomer at the National Radio Astronomy Observatory.
