Galactic Center Radio Arc

The Galactic Center Radio Arc is a long curving X-ray filament about 40 light years across located in the Galactic Center of the Milky Way galaxy (about 8 kiloparsecs). The Central Molecular Zone (CMZ) also contains the Galactic central radio arc. The structure is curving towards the Galactic Center where the supermassive black hole called Sagittarius A* is located.^[1][2]

The curving is due to the hot plasma located inside the Galactic Center Radio Arc being directed and flowing along constant and strong magnetic field lines.^[1][3]
