HIGH-VELOCITY MOLECULAR GAS IN THE GALACTIC CENTER RADIO LOBE

摘要

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 V_(LSR) ～+100 km s~(-1), and the western spur approaching at K_(LSR) ～—150 km s~(-1), suggesting a high-velocity rotation of the GCL. We study the kinematics of the GCL based on these molecular line data.
