Large-scale periodic velocity oscillation in the filamentary cloud G350.54+0.69
Large-scale periodic velocity oscillation in the filamentary cloud G350.54+0.69
We use APEX mapping observations of 13CO and C18O (2-1) to investigate the internal gas kinematics of the filamentary cloud G350.54+0.69, composed of the two distinct filaments G350.5-N and G350.5-S. G350.54+0.69 as a whole is supersonic and gravitationally bound. We find a large-scale periodic velocity oscillation along the entire G350.5-N …
