Title: Tracing the Radio Life of Galaxy Clusters
Abstract: Galaxy clusters are extraordinary laboratories for studying magnetized hot diffuse gas in the large-scale structure of the Universe. In fact, they provide some of the strongest evidence for large-scale magnetic fields through Mpc-scale diffuse radio emission. However, our limited understanding of the microphysics of the intracluster medium (ICM), as well as the complex interactions between galaxies and the surrounding plasma in these dense environments, remains a major challenge. In this talk, I will discuss the magnetization of galaxy clusters and the role of AGN activity, merger-driven shocks, and particle acceleration mechanisms such as diffusive shock acceleration (DSA) and turbulent re-acceleration in shaping the radio emission observed in these systems. I will present results from hybrid MHD simulations that include cosmic-ray (CR) modeling. Finally, I will highlight the power of new simulation-based inference frameworks that combine multi-wavelength observations with numerical simulations to better constrain cluster merger dynamics and the underlying physics of the ICM.
