A group of scientists in an article, which published in the book " The 2011 Fermi Symposium proceedings ", suggested that the giant X-ray "bubbles", which are regions of space filled with X-rays and symmetrically located nucleus of our galaxy, on the top and bottom of her core, and have supported by a periodic capture of stars of the supermassive black hole at the center of our galaxy. In their view, part of the star matter, falling into a black hole is ejected at high speed into the surrounding space, where collisions with the surrounding galactic core substance emits powerful X-ray radiation, which generates X-rays are "bubbles".
