Despite the enormous amount of data collected by astrophysicists, it was unknown where they came from.
Neutrinos are neutral particles thatdifficult to detect. They have almost no mass and practically do not interact with matter. They race through the Universe and can travel across galaxies, planets and the human body, leaving almost no trace.
"Astrophysical neutrinos are formedexclusively in processes related to the acceleration of cosmic rays,” explains professor of astrophysics Sarah Buson from the Julius-Maximilian University in Germany. Therefore, with the help of neutrinos, it will be possible to accurately determine the source of cosmic rays.
The main goal of the authors was to confirm one hypothesis. It was that blazars could be sources of extragalactic high-energy neutrinos.
To obtain these results, researchthe team used neutrino data from the IceCube neutrino observatory in Antarctica. With this data, the team proved that the direction of the blazars is the same as the direction of the neutrinos. And this, they say, is no coincidence.
