Cutout around our Coma replica with a side-length of d = 20 h⁻¹ c Mpc. The circles represent r₂₀₀ and r₅₀₀. From left to right, we show surface density, absolute value of the simulated magnetic field, CR electron energy of electrons with energies above 1 GeV, and turbulent reacceleration coefficient. The upper panels show the cluster in the full cosmological box; the lower panels show it in the zoomed-in re-simulation.
