袁峰研究员来访并作学术报告

Prof. Feng Yuan from SHAO visited SWIFAR

5月24号下午，上海天文台袁峰研究员应邀访问中国西南天文研究所，并为研究所及物理与天文学院师生作学术报告。

袁峰研究员主要从事黑洞天体物理、活动星系核以及星系形成与演化的研究。报告中，他介绍了利用其高分辨率二维流体动力学数值模拟方法研究活动星系核反馈机制的最新进展。报告结束后，师生们就数值模拟方法、活动星系核反馈机制的宇宙学影响等所关心的问题与袁峰研究员进行了互动交流。

袁峰研究员简介：

袁峰研究员于1997年获中国科技大学理学博士学位。1998年起至2005年先后在南京大学、德国马普射电天文研究所、美国哈佛大学、美国普渡大学进行博士后研究工作。2005年入选中科院“引进海外杰出人才”（百人计划），回国任上海天文台研究员。现任中科院上海天文台副台长、上海天文台学术委员会主任。主要研究方向为黑洞吸积与外流、活动星系核、星系形成与演化、黑洞X射线双星、系外行星形成等。

Prof. Feng Yuan from Shanghai Astronomical Observatory (SHAO) visited SWIFAR on May 24, 2018. He gave a colloquium presentation focusing on active galactic nuclei (AGN) feedbacks in isolated galaxies. The studies are based on high-resolution two-dimensional hydrodynamical simulations with the most-updated AGN physics included. By analyzing the light curve, typical lifetime and duty cycle of AGNs and star formation, he showed that their simulation results are in general agreements with the observations. After the talk, he had an extensive and stimulating discussion with the faculty members and the students at SWIFAR on numerical simulations and the potential to implement their detailed AGN feedback mechanism into cosmological simulations.

Personal Information:

Feng Yuan is now a research professor in Shanghai Astronomical Observatory (SHAO). He received his Ph.D. in astronomy in 1997 from University of Science and Technology of China. From 1998 to 2005, he worked as a postdoc at Nanjing University, Max-Planck Institute of Radio Astronomy, Harvard University, and Purdue University, respectively. He joined SHAO in 2005 under the CAS 100 telent program. His research interests include black hole accretion mechanisms, AGNs and their feedbacks on galaxy formation and evolution, black hole X-ray binaries, and planet formation.
