Age constraints for an M31 globular cluster from SEDs-fit
Jun Ma, Yanbin Yang, David Burstein +4
We have constrained the age of the globular cluster S312 in the Andromeda galaxy (M31) by comparing its multicolor photometry with theoretical stellar population synthesis models.…
Optical Monitoring of BL Lacertae Object S5 0716+714 with a Novel Multi-Peak Interference Filter
Jianghua Wu, Xu Zhou, Jun Ma +3
We at first introduce a novel photometric system, which consists of a Schmidt telescope, an objective prism, a CCD camera, and, especially, a multi-peak interference filter. The mu…
Membership Determination of Open Cluster M48 Based on BATC Thirteen-Band Photometry
Zhen-Yu Wu, Xu Zhou, Jun Ma +2
Beijing-Arizona-Taiwan-Connecticut (BATC) multi-band photometric data in the field of open cluster M48 are used to determine its membership. By comparing observed spectral energy d…
Evolution of Galaxy Luminosity Function and Luminosity Function by Density Environment at 0.03<z<0.5
Lifang Xia, Xu Zhou, Yanbin Yang +2
Using galaxy sample observed by the BATC large-field multi-color sky survey and galaxy data of SDSS in the overlapped fields, we study the dependence of the restframe -band gala…
Optical Monitoring of BL Lacertae Object OJ 287: a 40-Day Period?
Jianghua Wu, Xu Zhou, Xuebing Wu +6
We present the results of our optical monitoring of the BL Lacertae object OJ 287 during the first half of 2005. The source did not show large-amplitude variations during this peri…
