[Ne II] Observations of Gas Motions in Compact and Ultracompact H II Regions
Qingfeng Zhu, John H. Lacy, Daniel T. Jaffe +2
We present high spatial and spectral resolution observations of sixteen Galactic compact and ultracompact H II regions in the [Ne II] 12.8 microns fine structure line. The small th…
Radial Velocities of Stars in the Galactic Center
Qingfeng Zhu, Rolf P. Kudritzki, Donald F. Figer +2
We present results from K band slit scan observations of a ~20''x20'' region of the Galactic center (GC) in two separate epochs more than five years apart. The high resolution (R>=…
Mass Flows in Cometary UCHII Regions
Qing-Feng Zhu, John H. Lacy, Daniel T. Jaffe +2
High spectral and spatial resolution, mid-infrared fine structure line observations toward two ultracompact HII (UCHII) regions (G29.96 -0.02 and Mon R2) allow us to study the stru…
