High-Velocity Molecular Gas in the Galactic Center Radio Lobe

Abstract

We point out a possible association of high-velocity molecular gas with the Galactic Center Radio Lobe (GCL). A molecular spur in the eastern GCL ridge is receding at $\Vlsr \sim +100$ \kms, and the western spur approaching at $\Vlsr \sim -150$ \kms, suggesting a high-velocity rotation of the GCL. We study the kinematics of the GCL based on these molecular line data.
