An international team of astrophysicists, with the participation of the National Nuclear Research University, discovered a signal from high-energy photons emitted by galaxies in Fermi data.
The discovery highlights the origin of high-energy neutrons recorded by the "IceCube" neutron observatory of the Antarctica-Tscott Antarctic Station. According to Physical Review-D.
The neutrino passes through the places where other particles stumble. For example, the solar neutrino crosses the depths of the sun and provides information on thermonuclear interactions in the sun's core.
High energy neutrons have so far invaded the mysterious outer space, providing information that can not be obtained by other methods of observation.
"At energies up to 300 GHz, signals from sources outside our galaxy will be suppressed by the absorption of rays," said Dimitri Semikoz, a professor at the University of Mivie, in an interview with one of the authors, RIA Novosti. Gamma in the intergalactic space, while remaining parallel to the galactic distances Gamma rays are not absorbed in practice, the new component must have a source in our galaxy. "
