| Abstract: |
We present high-resolution VLA observations of the Galactic Center Radio Arc with improved bandwidth and frequency coverage. We find a complex total intensity environment surrounding the Radio Arc non-thermal filaments. The polarized intensity is characterized by emission that extends into regions of low total intensity. In addition, we show the rotation measure and intrinsic magnetic field distributions for the Radio Arc. The magnetic field orientation alternates between being parallel and rotated with respect to the orientation of the Arc NTFs. The rotated regions of magnetic field may indicate the presence of an additional magnetized structure local to the Radio Arc. |
