摘要/Abstract:

Galaxy clusters, as massive, virialized halos within the cosmic web, serve as ideal laboratories for advancing our understanding of cosmology, plasma physics, and the nature of dark matter. The study of their formation and evolution represents one of the frontiers of modern astrophysics. In this talk, I will discuss several cutting-edge topics in cluster research, ranging from the activity of supermassive black holes at cluster centers to gas accretion and violent mergers in the outskirts. I will highlight our recent progress in mapping gas kinematics with the XRISM X-ray Observatory and demonstrate the power of idealized numerical simulations in probing complex physical processes and interpreting observational data.

个人简介/Biography:

Congyao Zhang is currently a postdoctoral researcher at Masaryk University in the Czech Republic. He received his PhD from the Kavli Institute for Astronomy and Astrophysics (KIAA) at Peking University in 2016, and subsequently held postdoctoral and research scientist positions at the Max Planck Institute for Astrophysics (MPA) and the University of Chicago. His research interests include galaxy clusters, large-scale structures, and cosmology. He recently joined the XRISM collaboration and has led several projects focused on mapping cluster gas kinematics.
