Simulated radio emission up to z=1

Integrated radio emission from a 14x14 degree field, containing all projected cosmological volume up to z=1 (obtained by stacking several boxes along the line of sight). Each dataset is 1200x1200x11, where each frame gives the evolution of the projected emission by adding up the contribution of an increasing volume. The units are log10[J/arcsec^2] and the emission is computed at 110 MHz. The 5 different models represented in each .fits are: MHD=magnetic field from the MHD simulation, starting from a cosmological B0=1e-10G at z=30. HA=the magnetic field from the MHD run is renormalized to be 1% of the gas energy of cells, whenever n>2n_critical ("high-amplification" model) LA=as in HA, but only for n>50n_critical ("low-amplification"model) HSA=as in HA + CR-driven amplification for strong shocks. Each .fits has a number related to the simulated model: 0=no reacceleration, HA model; 1=HA and shock injection+re-acceleration; 2=LA and shock injection+re-acceleration; 3=HSA and shock injection+re-acceleration; 4=original MHD, shock injection and re-acceleration. The "spectrum" .fits files give the emission weighted radio spectrum for each frame of the above models. The "cluster" fits give the location of clusters (within Rvir) as measured with an halo catalog. The "density" fits give the projected gas density map (actually density^2) as more volume is added up. The "clean" fits give the maps of emission after excising the regions covered by the virial sphere of clusters.
