H-alpha +[NII] Observations of the HII Regions in M81
W. P. Lin, X. Zhou, D. Burstein +2
In a first of a series of studies of the H-alpha + [NII] emission from nearby spiral galaxies, we present measurements of H-alpha + [NII] emission from HII regions in M81. Our meth…

Jun Ma, Xu Zhou, Jiansheng Chen +5
This paper is the fourth in a series presenting spectrophotometry of 51 globular cluster candidates, that were detected by Mochejska et al. in the nearby galaxy M33 using the data…
SED, Age and Metallicity of Star Clusters in M33
Jun Ma, Xu Zhou, Xu Kong +5
In this paper we present CCD spectrophotometry of the star clusters that were detected by Chandar, Bianchi, & Ford in the nearby spiral galaxy M33, using the images obtained with t…
Deep Intermediate-Band Surface Photometry of NGC 5907
BATC Collaboration, Z. Y. Zheng, Z. H. Shang +3
We obtained very deep exposures of NGC 5907 with a Schmidt telescope, large-format CCD, and intermediate-band filters centered at 6660A and 8020A. These two filters, part of a 15-f…
