The Ages of M31 Star Clusters: Spectral Energy Distribution Versus Color-Magnitude Diagram
Zhou Fan, Zhongmu Li, Gang Zhao
It is well-known that fitting the Color Magnitude Diagrams (CMDs) to the theoretical isochrones is the main method to determine star cluster ages. However, when the CMDs are not av…
Gluon Quasi-PDF From Lattice QCD
Zhou-You Fan, Yi-Bo Yang, Adam Anthony +2
We present the first attempt to access the -dependence of the gluon unpolarized parton distribution function (PDF), based on lattice simulations using the large-momentum effecti…
Testing Area of the SAGE Survey
Jie Zheng, Gang Zhao, Wei Wang +4
Sky survey is one of the most important motivations to improve the astrophysics development, especially when using new photometric bands. We are performing the SAGE (Stellar Abunda…
The SAGE Photometric Sky Survey: Technical Description
Jie Zheng, Gang Zhao, Wei Wang +4
To investigate in more details of Stellar Abundance and Galactic Evolution (SAGE) and in a huge sample, we are performing a northern sky photometric survey named SAGES with the SAG…
Investigating the Efficiency of the Beijing Faint Object Spectrograph and Camera (BFOSC) of the Xinglong 2.16-m Reflector
Yong Zhao, Zhou Fan, Juanjuan Ren +7
The Beijing Faint Object Spectrograph and Camera (BFOSC) is one of the most important instruments of the 2.16-m telescope of the Xinglong Observatory. Every year there are ~ 20 SCI…
Upgraded Photometric System of The 85-cm Telescope at Xinglong Station
Chunhai Bai, Jianning Fu, Taoran Li +8
The 85-cm telescope at the Xinglong station is a well-operated prime focus system with high science outputs. The telescope has been upgraded since 2014 with new corrector, filters…
