Title: Magnetic Turbulence and Reconnection in Galaxy Clusters: toward the Era of Square Kilometre Array 
Place: ES635 & ZOOM
Abstract: The intracluster medium (ICM) in galaxy clusters is expected to be magnetized and turbulent. But the origin and nature of the magnetic field poorly understood, remaining its true impact into the cosmology and the structure formation theory open. Recent astronomical telescopes such as XRISM in X-rays and SKA Pathfinders and Precursors in long-wavelength radio have been focusing on solving these problems. In my talk, I briefly recap a theory of magnetic turbulence and reconnection, then introduce our two radio observations of Abell 3322 and CIZA 1410, which bring new insights into magnetic turbulence and reconnection in galaxy clusters.
