Individual panels showing the phase-space diagrams in the density-synchrotron emissivity phase-space, containing all gas particles in the simulation. The background shows mass histograms per phase-space element from the original simulation output. The colored lines indicate the mean synchrotron emissivity per density interval for the cosmological box simulation and the zoom-in simulations with and without turbulent reacceleration. All emissivities are calculated at a frequency of ν = 144 MHz. The upper limit of the synchrotron emissivity is taken from Hoang et al. (2023).
