Energy distributions of the tracers inside R₅₀₀ at two different redshifts, marking an epoch before (10.86 Gyr) and after (12.65 Gyr) the last important merger in the system, and the onset of diffuse radio emission. Top-left: distribution of the ratio between the CR energy and the turbulent energy. The ratio increases with time and broadens after the merger; top-right: distribution of the CRe energy; bottom-left: kinetic, or turbulent, energy distribution; bottom-right: the gas energy distribution.
