A Near-Infrared Study of the Stellar Cluster: [DBS2003] 45 (2009)
Zhu, Qingfeng, Davies, Ben, Figer, Donald F., Trombley, Christine
We present a multi-wavelength photometric and spectroscopic study of a newly discovered candidate cluster [DBS2003] 45. Our H, Ks photometry confirms that [DBS2003] 45 is a cluster. An average visual...
[Ne II] Observations of Gas Motions in Compact and Ultracompact H II Regions (2008)
Zhu, Qingfeng, Lacy, John H., Jaffe, Daniel T., Richter, Matthew J., Greathouse, Thomas K.
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 thermal width of the...
Radial Velocities of Stars in the Galactic Center (2008)
Zhu, Qingfeng, Kudritzki, Rolf P., Figer, Donald F., Najarro, Francisco, Merritt, David
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>=14,000)...
