Left: FIR luminosity between 8 and 1000 μm, and the 1.4 GHz monochromatic power, i.e., the quantities used to estimate the kinetic energy of the different possible drivers discussed in this paper. The yellow filled, red hatched, and green hatched diagrams correspond to bolometric AGN power, star formation, and radio power, respectively. We only include sources with Herschel detections. Right: same histograms showing the kinetic energy corresponding to the FIR luminosity and monochromatic radio power at 1.4 GHz, derived with the methods described in Sects. 5 and 6.
