Abstract：

Understanding the co-evolution of supermassive black holes and their host galaxies is currently one of the frontiers in galaxy evolution. The physical processes of active galactic nuclei (AGN) affecting the growth of their host galaxies are intensively studied. Using multi-wavelength observations and focusing on AGN feedback and star formation at different scales, I will give an overview on the progress in our understanding and relevant findings in recent years. Through a series of discoveries (hot gas halo around galaxy merger, quasar "super bubbles", ionized gas relics, jet-cloud interaction), we present observational evidence of feedback from inner-most nuclear region to the circum-galactic medium scale.

CV：

Dr. Junfeng Wang received his Bachelor's degree from Department of Astronomy at Nanjing University in 2001 and obtained his PhD degree at Pennsylvania State University in 2007. He then worked as a postdoctoral fellow at the Harvard-Smithsonian Center for Astrophysics for 4 years, before moving to Northwestern University as a Research Assistant Professor and CIERA Fellow. In 2013 he joined Department of Astronomy at Xiamen University as MinJiang Professor. He is specialized in multiwavelength observations of active galaxies, and has been Principal Investigator of multiple NSFC projects and a dozen NASA/ESA programs. His main research interests are galaxy formation and evolution, in particular co-evolution of supermassive black holes and their host galaxies. He has published over 100 papers in major astronomical journals, with an H-index of 32.
