| dc.description | 32 GHz observations with the Effelsberg 100-m telescope revealed a highly polarized Galactic Centre filament: G0.087-0.087, running parallel to the well-known Arc structure. It has a similar flat spectrum, but it is an order of magnitude weaker. G0.087-0.087 is about 2.5' or 6.2 pc long and located at the western boundary of the expanding molecular cloud G0.11-0.11. This unusual cloud is also visible in X-rays and known to interact on its eastern periphery with the Arc. Acceleration of highly relativistic particles at the surface of G0.11-0.11 seems necessary to explain the properties of both structures. The new filament supports previous findings on the existence of a strong poloidal magnetic field throughout the Galactic Centre region. | |
