Emission from our simulated light cone at z = 0.03, z = 0.05 and z = 0.5, obtained by stacking replicas of our (100 Mpc)³ and (200 Mpc)³ simulated volumes. The top panels show the total X-ray emission proxy (∝ n²T^1/2) and the lower panels show the radio emission for LOFAR-LBA (units of log ₁₀ [Jy/arcsec²]) for a projected area of 3.5° × 3.5°, assuming the high-amplification model (HA). The white contours of the X-ray emission proxy are drawn in the lower panels to allow a better comparison of structures.
