Hello

My name is Yang Yang (杨阳). I am currently a faculty at Xiangtan University, Xiangtan, Hunan, China (joined in 2025.05). Before joining Xiangtan University, I was a postdoctoral researcher at the Purple Mountain Observatory (PMO, 2022-2025), and Shanghai Astronomical Observatory(SHAO, 2017-2022), Chinese Academy of Science.
I completed my Ph.D. in Astrophysics in 2017.03 at Nanjing University in China, supervised by Prof. Zhiyuan Li at Nanjing University. I then did my postdoctoral research with Prof. Jiangtao Li at PMO, and with Prof.Zhiqiang Shen at SHAO.
My research primarily focuses on studying the feedback mechanisms of active galactic nuclei (AGNs) and HI gas in nearby galaxies. As a member of the Continuum Halos of Nearly Galaxies – an EVLA Survey (CHANG-ES) , I have extensively analyzed deep VLA radio data to understand AGN feedback activity at various scales. This involves investigating how AGNs impact their surrounding environment and the role they play in galaxy evolution. I am familiar with both the observation and data reduction processes involved in utilizing the VLA. By employing multi-band observational results, I have explored the influence of nuclear activity on the surrounding medium, allowing for the clearest observable evidence in unraveling the complexities of AGN feedback.
More recently, I have broadened my research interests to include the study of the cold circumgalactic medium (CGM) within galaxies and galaxy clusters. I am leading a new observational research project HIMALAYA, on the extended HI gas disk of massive disk galaxies. Even more, I will expand my research into high-redshift galaxies with our new CO observations.
