Scientific paper

By filtering out the straight filaments of the Galactic Cente Arc in VLA radio images of Yusef-Zadeh and Morris, we show that numerous concentric radio shells and arcs of radii 5 to 10 pc are coherently surrounding the Pistol and Sickle region. Each shell has a thermal energy of the order of 1049 ergs. Several CO-line shells are found toward the radio shells with kinetic energy of the order of 1049-50 ergs. We propose a new idea that the concentric shell structure has the common origin: they are expanding fronts from intermittent outflows and/or ionization due to successive star-forming activities near to the Pistol and Quintuplet stars.
