Description

In the past two decades, a link between giant radio haloes and their host clusters’ dynamical state was established, with radio haloes detected in merging systems. It is not clear at which stage of the merger the cluster emits these synchrotron radio emissions. Our main aim is to investigate the dynamical states of galaxy clusters detected to host diffuse radio emission (haloes, relics, etc.). We will investigate the line-of-sight substructure, since we expect such substructures to be present, and measure the dynamical mass of the merging components. We will also use multi-wavelength data (radio, optical and X-ray) to constrain the merging geometry and time scales in the lifecycle for giant radio haloes. This will help us better understand the origins and evolution of these energetic sources.
