The clue to the origin of high-energy neutrinos in space: astrophysicists from Russia are close to that secret

The clue to the origin of high-energy neutrinos in space

Scientists from Russia came closer to the clue to the origin of high-energy neutrinos. They reported that they track mysterious particles, and this is done in such a place that will surprise many people. For their research, specialists from the Moscow Institute of Physics and Technology use the RATAN-600 telescope. With it, they find out the origin of cosmic particles from black holes in distant quasars.

A team of scientists was able to compare elusive particles collected by the IceCube Antarctic Neutrino Observatory. And a comparison was made of long electromagnetic waves, which were measured by radio telescopes. As it turned out, cosmic neutrinos are directly related to flares that occur in the centers of distant "living" galaxies.


Scientists believe that there may be supermassive black holes. Matter, being close to a black hole, accelerates and ends up in outer space, causing the formation of neutrinos that begin to move around the universe with the speed that is close to the speed of light. Neutrinos are hypothetical particles, even the mass of which is unknown to science.

But there is an assumption that neutrinos are able to pass through objects and people. High energy neutrinos can be created when protons accelerate almost to the speed of light. Russian scientists decided to focus on the origin of ultrahigh-energy neutrinos at 200 trillion electron-volts or more.

They studied the data of the IceCube measuring instrument located in the Antarctic ice. It has a wide range of radio observations, with their help, researchers discovered elusive particles that arose in the centers of quasars during radio frequency flashes.


Quasars in some galaxies are sources of radiation. There is a black hole in it, absorbing all the matter located in the disk surrounding the quasar, while emitting powerful flows of ultrashort gas.

Alexander Plavin, one of the researchers, believes that the results demonstrate the fact that high-energy neutrinos are formed during radio bursts in the active nuclei of galaxies. Scientists analyzed 50 similar events and found out that particles come from bright quasars and a network of radio telescopes is able to fix thi.
