Maps of the total number of CRe (injected by shocks only, in units of [log₁₀(N_CRe)]) along the LoS of a 10 × 10Mpc² zoomed region in our test runs, where we included all sources of feedback in the simulation (’baseline’ model, as in the main paper) or we switched off AGN feedback (’no AGN’) or stellar feedback (’no SF’), or both (’no SF no AGN’). The red circles identify regions in which obvious differences are visible between models, while the green lines show the direction for which we generated radial profiles of the number of CRe in Fig. A.4.
