A Dynamic View of Galaxy Clusters – From the Cores to the Outskirts

张从尧 (University of Chicago)


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 stands as one of the frontiers of modern astrophysics. In this talk, I will cover several key topics in cluster studies, from the activities of supermassive black holes at cluster centers to accretion and violent mergers at the outskirts. I will demonstrate the power of idealized numerical simulations in exploring the physical processes within clusters, such as feedback, turbulence, shocks, and halo virialization. Additionally, I will discuss several X-ray missions/mission concepts (e.g., XRISM, LEM), highlighting our recent progress in understanding turbulence in the Perseus cluster using new XRISM data.


· Research Scientist at University of Chicago. Moving to Masaryk University later this year
· Congyao got PhD degree from Peking University in 2016, and worked at Max Planck Institute for Astrophysics (MPA) before joining University of Chicago.
· His research interests include galaxy clusters, large-scale structures, and high-energy astrophysics.

· He is actively involved in multiple international teams for the development of X-ray missions/mission concepts, such as XRISM, LEM, and Athena.
