Energy injection rates into gas cells of Halo3 in the radiative simulation are shown. The panels differentiate between feedback launched from the BCG center (r < 20 kpc; left panel) and from the rest of the cluster, excluding the center (right panel). We present different energy injection rates that originate from stellar feedback (yellow) as well as thermal (purple) and kinetic (orange) AGN feedback. The injected thermal AGN feedback (dashed purple) is numerically reduced in star-forming cells where an effective equation of state is enforced, implying a rapid energy loss and a smaller effective thermal AGN feedback energy rate (solid purple). Radiative cooling losses (blue) are displayed for the ICM in the right panel. At high redshifts, both in the BCG and the entire cluster, the primary energy injection rate is due to stellar feedback. Subsequently, AGN feedback also becomes a significant contributor.
