Astronomers got an image of the Milky Way created using neutrinos. This was reported by the University of Wisconsin-Madison.
Neutrinos are a class of elementary particles that interact extremely weakly with ordinary matter. For example, a significant portion of the Sun’s energy is spent emitting neutrinos, but they pass through the Earth without any effect. Only sophisticated and large detectors can detect these particles.
Now astronomers synthesized Neutrino image of the Milky Way based on IceCube data. This observatory is located in Antarctica at the Amundsen-Scott polar station and covers one cubic kilometer of Antarctic ice, on which 5,000 neutrino sensors are deployed. The researchers developed an algorithm that helps astronomers reconstruct the precise trajectories of more than 60,000 neutrinos, whose traces of transit through Earth’s atmosphere and rocks were detected by the IceCube detectors over the last 10 years of this setup’s operation. Using this data, the scientists created a three-dimensional map of the motion of neutrinos in space and compared it to where the possible sources of these particles should be. Neutrino sources are shown in blue in the published image.
Including astronomers, they were able to confirm that a significant portion of previously discovered neutrinos came from our galaxy. Interactions between cosmic rays and galactic gas and dust produce both gamma rays and neutrinos, so scientists are not surprised that the Milky Way is a source of high-energy neutrinos.
