中国空间站光学巡天望远镜宇宙学工作组会议召开

Chinese Space Station Optical Survey Telescope 

Cosmology working group meeting held at SWIFAR

2019年8月12-14日，中国空间站光学巡天望远镜（CSST）宇宙学工作组会议在云南大学中国西南天文研究所召开。来自国家天文台、紫金山天文台、上海天文台、上海交通大学、中山大学、云南大学等国内高校和科研机构的20余位宇宙学研究学者参加了此次会议。

此次会议围绕CSST项目的宇宙学研究科学目标，深入讨论了目前各工作组的研究进展、数据需求以及下一步研究路线图等。会议对进一步推动CSST的宇宙学研究起到了积极的促进作用。

On August 12-14, 2019, Chinese Space Station Optical Survey Telescope (CSST) Cosmology working group meeting was held at SWIFAR, Yunnan University. Over 20 scientists from National Astronomical Observatories, Purple Mountain Observatory and Shanghai Astronomical Observatory of Chinese Academy of Sciences, Shanghai Jiao Tong University, Sun Yat-sen University and Yunnan University attended the meeting.

The CSST is scheduled for launch in 2024. As a stage IV space-borne survey facility, it aims to probe the Universe with unprecedented precisions. Its unique high angular resolution and multi-band design make it powerful complementarities to other stage IV surveys, such as Euclid and LSST. Participants discussed in depth the latest work progress, the working road map, data requirements, and other issues. This meeting was helpful to further push forward the science preparation of CSST.
