报告题目：ALMA observations of massive clouds in the Central Molecular Zone: Jeans fragmentation, ubiquitous outflows, Keplerian disks, and other upcoming results

　　报 告 人：吕行 研究员（上海天文台）

　　报告摘要：I will introduce our recent results about star formation in the Central Molecular Zone around the Galactic Center using ALMA observations, including thermal Jeans fragmentation of dense gas, ubiquitous protostellar outflows, and the discovery of a massive protostellar disk that follows Keplerian rotation. While focusing on star formation activities, we also make use of the obtained data to explore astrochemistry, shocks, and other espects of the ISM evolution. These high-risk, high-reward ALMA data will allow us to gain a comprehensive view of star formation in the extreme environment around the Galactic Center, and will constitute a great sample to be compared with star formation activities in nearby molecular clouds.
