Abstract：Galaxies, as fundamental structural units of the universe, possess ecosystems shaped by multiple physical mechanisms including star formation, gas accretion, and feedback processes. Dynamic balance and evolution are achieved through complex mass and energy cycles among their components. Understanding such co-evolution between supermassive black holes (SMBHs) and their host galaxies represents a frontier topic in current galaxy evolution research. It is envisioned that Active Galactic Nuclei (AGN) and stellar feedback can significantly influence host galaxy growth through multi-scale physical processes. Based on multi-wavelength data, this talk presents observational studies related to AGN feedback, and some recent results from high-resolution observations such as the validation of the physical coupling between cold and hot gas in stellar feedback.
Bio：Wang Junfeng is a Professor in the Department of Astronomy at Xiamen University. He received his B.Sc. in Astronomy from Nanjing University in 2001 and his Ph.D. from Pennsylvania State University in 2007. He subsequently held postdoctoral and research assistant professor positions at the Harvard-Smithsonian Center for Astrophysics and Northwestern University. In 2013, he joined Xiamen University. His primary research area is galaxy formation and evolution, particularly utilizing multi-wavelength observations to study the impact of supermassive black holes on their host galaxies. He has published over 130 papers in leading astronomy journals, with an H-index of 35. He currently serves as Associate Chair of the Galaxy and Cosmology Committee of the Chinese Astronomical Society, Subject Editor for Progress in Astronomy, and Young Editorial Board Member for Chinese Physics Letters (CPL).
