学术报告—Development Progress and Characteristic Scientific Examples/Preparations of CSST-MCI

摘要：

自1990年发射入太空，哈勃空间望远镜（HST）在其在轨运行的33年时间里，为天文和天体物理领域带来了诸多革命性的发现。然而，哈勃空间望远镜很可能在今后几年内停止运行，之后其在紫外和光学波段的角色有望被中国空间站巡天空间望远镜（CSST）所替代。在本次报告中，我将简单为大家介绍HST和CSST，之后重点介绍CSST的多通道成像仪（MCI）载荷。多通道成像仪是CSST的首批五台载荷之一，它是由上海天文台和上海技术物理所联合研制，它是类比哈勃太空望远镜第三代广域相机WFC3的设计，但有其独特优势。我将介绍多通道成像仪的设计、研究现状和它的主要科学目标，重点展示其在系外行星、恒星、星系等领域的科学示例及准备。

Since its launch in 1990, the Hubble Space Telescope (HST) has revolutionized our understanding of the universe during its 33 years in orbit. However, HST is likely to stop operating in the next few years, and its role in the ultraviolet and optical astronomy is expected to be replaced by the China Space Station Telescope (CSST). In this talk, I will briefly introduce HST and CSST, and then focus on the Multi-Channel Imager (MCI) payload of CSST. As one of the first five payloads of CSST, MCI is jointly developed by Shanghai Astronomical Observatory and Shanghai Institute of Technical Physics. It is similar to the design of the WFC3 of the Hubble Space Telescope but has its unique advantages. I will introduce the design, research status, and main scientific objectives of MCI, focusing on its scientific examples and preparations in the fields of exoplanets, stars, galaxies, etc.
