The ionized gas in the Galactic Center Radio Arc
/ Authors
/ Abstract
The Radio Arc is one of the most prominent radiocontinuum features in the Galactic center region. It is composed by long and thin filaments that emit non-thermal radiation (Non-Thermal Filaments; NTFs) and indicate the presence of a strong component of the magnetic field perpendicular to the Galactic plane. The Arc is apparently connected to Sgr A by a ‘bridge’ of arched filaments that emit thermal radiocontinuum (Thermal Filaments). There are two other thermal sources in the vicinity of the NTFs: the Sickle and the Pistol Nebula.
