Radio surface brightness map (top) and multiwavelength map (bottom) in three different projections of the same TNG-Cluster merging cluster as in Fig. 1. The yellow circles mark R_500c (1.7 Mpc) and R_200c (2.8 Mpc) from the cluster center. The green and white contours on the X-ray map depict radio surface brightness and mass surface density, smoothed with σ = 10 and 20 kpc Gaussian kernels and spaced equally in logscale in between [10²⁴,  10²⁷] erg s⁻¹ Hz⁻¹ kpc⁻² and [10^8.3,  10^9.3] M_⊙ kpc⁻², respectively. The clearly visible double radio relics are elongated tangentially with respect to the mass center and their LLS measures ∼4 Mpc. Moreover, they form a nonuniform radio halo-like feature in the z-axis projection that fills the cluster volume to R_500c. The total radio power of these structures is P_1.4 GHz ∼ 10²⁵ W Hz⁻¹.
