Galactic Center teems with the most extremal and exotic objects. Among them are so-called filaments — long and thin structures. Some of them are visible in radio, the other — in X-rays. They are supposed to appear as a result of relativistic electrons' and positrons' synchrotron radiation. These particles are born near pulsars — rotating neutron stars with strong magtic fields. New observations support this hypothesis.

This finding confirms the hypothesis that the supermassive black hole in the center of our Galaxy once had been much more active that it is now. The results are published in the Nature journal.
