中科院上海天文台袁峰教授访问中国西南天文研究所

Prof. Feng Yuan from Shanghai Astronomical Observatory, CAS visited SWIFAR

2020年8月9日至13日，中国科学院上海天文台副台长袁峰教授应邀访问新利18体育新，并分别于8月11日和12日为研究所及物理与天文学院师生作系列学术讲座。

袁峰教授研究领域主要集中在黑洞和吸积盘，特别是利用相对论框架下的磁流体数值方法模拟吸积盘的物理过程及其与宿主星系的协同演化等问题。此次访问中，他为师生们讲解了吸积盘的基本物理过程及其对宿主星系演化的影响，着重介绍了其团组近年来利用计算机模拟对相关问题进行的深入研究和成果。师生们从中获益良多，并与袁峰教授进行了深入交流。访问期间，袁峰教授亦与研究所科研人员就不同科学课题和未来进一步合作展开了讨论。

袁峰教授简介：

袁峰教授于1997年获得中国科学技术大学天体物理博士学位。之后分别于南京大学，德国马普射电天文所，哈佛大学和普渡大学从事博士后研究。2005年加入上海天文台，现任上海台副台长。主要研究领域包括黑洞的吸积与喷流，活动星系核，星系演化等。

From August 9 to August 13, 2020, Prof. Feng Yuan from Shanghai Astronomical Observatory, CAS, visited SWIFAR. He presented a lecture on AGN physics and a colloquium on numerical studies of AGN feedbacks.

In the lecture, Prof. Yuan introduced the basic concepts of AGN and accretion process to the students. In his colloquium, he focused on feedbacks arising from the accretion of supermassive black holes, which are believed to play a crucial role in galaxy evolution. He showed their recent simulation studies. The lecture and colloquium were very well received, and stimulated extensive discussions. During his visit, Prof. Yuan also discussed with SWIFAR faculty members on potential collaborative projects.

Brief introduction of Prof. Feng Yuan:

Feng Yuan is a professor at Shanghai Astronomical Observatory, Chinese Academy of Sciences. He obtained his Ph.D. in USTC in 1997, then worked at Nanjing University, Max-Planck Institute of Radio Astronomy in Germany, Harvard University, and Purdue University in the US as a postdoc. He joined Shanghai Astronomical Observatory in 2005 and now serves as the deputy director there. Prof. Yuan’s research interests include physics of black hole accretion and outflow, active galactic nuclei, and galaxy evolution.
