New model developed by IKI astrophysicists and their colleagues and based on the data of SRG/eROSITA X-ray telescope, links the bright structure seen in our Galaxy to bubbles of hot gas that emerge from star-formation regions like smoke from the chimney.

New model developed by IKI scientists and their colleagues from Ioffe Institute sheds new light on the origin of W50 giant radio nebula, which hides the most reknown X-ray object of our Galaxy – SS433 microquasar.

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.

Astrophysicists from IKI and Ioffe Institute, using the data from SRG/eROSITA space telescope, studied the properties of a shock in Coma cluster of galaxies. The paper summarising their results was accepted for publication in Astronomy&Astrophysics.
