Astronomers were able to identify for the first time the source of high-energy cosmic neutrons recorded by the IceCube Observatory several years ago. The scientists concluded that particles with energies hundreds of times more than the protons in the large hadron collider, gave birth to the blazar – an active core of the galaxy, whose light went to Earth a few billion years ago. ; years. This result marks a new stage in the development of multi-channel astronomy and confirms the idea that blacksmiths are sources of high-energy cosmic rays

One of the most important tasks in the study of high energy astrophysical neutrino cosmic rays. These particles are thought to arise from the collapse of mesons formed in or near cosmic "accelerators" when cosmic rays interact with atomic nuclei and photons
Because neutrinos are very light, no charge, and interact only with the substance At very small subatomic distances, scientists are able to determine from the energy spectrum of the recorded particles and in the sense of their arrival to determine what processes occur in a distant astrophysical object.
The rhonomis knew of the existence of two well-identified sources of astrophysical neutrinos: the Sun and the 1987A supernova, which erupted in the nearby Big Galaxy Cloud Galaxy with us. However, the neutrinos recorded from them have energies in millions of times lower than the observed high energy neutrino flux observed, so the nature of the mechanisms to generate high energy cosmic neutrinos and the search for their sources remains opened. The research complicates the need for large detectors, and the small amount of data currently collected at the time of the statistic.
One of the existing and effective detectors of the IceCube of the Neutrino Observatory, located in Antarctica. The system has a volume of one cubic kilometer (hence the name) and consists of 5000 optical sensors, which are located on 86 vertical "wires" at a distance of 125 meters and are located at depths from 1450 to 2450 meters in the thickness of the ice.

Due to the interaction of neutrinos with ice and soils, muons form . which records the sensors, which allows us to estimate the neutrino energy and the direction of the particles hu ro. Earlier, the Observatory recorded a reliable record of astrophysical neutrino flux, and last year it was able to capture three neutrinos for the first time
On September 22, 2017, an automatic detection system recorded the event IceCube-170922A, 20-54 by Greenwich, "formed during the interaction of high energy neutrinos with ice. Registration notifications have been sent to d & # 39; other observers, including the ANTARES neutrino (astronomy with a neutrino telescope and Abyss environmental RESEARCH), which, however, did not record anything in the day following the recording of the event and before him [19659011] .The Fermi space gamma observatory reported that a certain direction of arrival of neutrinos recorded with an average energy of 290 TEV corresponded to known sources of gamma rays in a state of high activity .
There s & # 39; acts d & # 39; an active galaxy located there n & # 39; not long ago. Eco left shoulder of the constellation Orion. The light of the source has reached Earth four billion years ago.
Another wave of gamma radiation from this source has been confirmed by a number of Cherenkov terrestrial telescopes, particularly the Magnetic Atmospheric Gamma Imaging Cherenkov Telescope (TCHM) and the High-Energy Stereoscopic System (HESS).
These observations provide a fairly complete and simultaneous picture of the recording of particles and radiation of blacksmiths in the energy range of 0.3 kV to 400 gigaelectronvolt
An analysis of archived data from IceCube detector has detected more than a dozen astrophysical neutrino recording events since early November 2014 from the same source with great certainty.
Astronomers point out that this is a significant achievement for multi-channel astronomy (Multi-Messenger Astronomy, MMA), a branch of science that has been put into the forefront with the simultaneous recording of gravitational waves and the triggering of Kilonov from the fusion of neutron stars. Similar observations of astrophysical objects and processes are performed simultaneously on different telescopes, which allows us to get a more complete picture of what is happening and to check existing theories.
Cosmic rays attract the attention of scientists for at least 100 years. They represent nuclei of atoms and elementary particles that move in space and have the highest energies observed in nature. The energy of some particles far exceeds that which can be achieved with the help of modern accelerators – it ranges from 109 to 1020 MeV (mega-electronvolts). The composition and distribution of energy particles can provide a lot of information on the structure of the universe.
Earlier, it was reported that very high energy cosmic rays have an extragalactic character, but no precise source could be established. It was assumed that they could be supernova explosions, gamma-point sources, or active galactic nuclei containing supermassive black holes.
