摘要 (Abstract): 

       The Chinese Space Station Optical Survey (CSS-OS) is a major science project of China Manned Space Program. It will be carried out by a 2m off-axis telescope in the same orbit as the Chinese space station, starting around 2024. The survey plans to cover roughly 17,500 square degrees of the sky at a resolution of 0.15" in at least 6 broadband filters from 250nm to 1000nm, reaching an average depth of AB 25.5 mag (point source, 5-sigma). Low resolution slitless spectra will be taken the same time over the same area reaching a depth of AB 20-21 mag per wavelength resolution. In this talk I will give a brief update on the project and discuss the expected performance from simulations.

主讲人简介 (Speaker's CV): 

Hu Zhan is a professor at the National Astronomical Observatories of China (NAOC) with a joint appointment at the Kavli Institute for Astronomy and Astrophysics at Peking University. He obtained his Ph.D. from the University of Arizona in 2004 and then spent 5 years at the University of California at Davis working on the Large Synoptic Survey Telescope (LSST). In 2009, he joined NAOC with the support of Hundred Talents Program from the Chinese Academy of Sciences. Prof. Zhan's research interest is mainly on cosmology and astronomical imaging technology. Currently, he is leading a team to build the large mosaic camera for the Chinese Space Station Optical Survey.
