We study a sample of 1,684 moderate-to-high radiative luminosity AGN (HLAGN) within the VLA-COSMOS 3GHz Large Project. These were selected by combining X-ray with MIR data and by selecting AGN based on their SEDs. We derive luminosity functions for these AGN and constrain their cosmic evolution out to a redshift of 𝑧~6, for the first time decomposing the star formation from AGN contributions to the radio continuum emission in the AGN. We find a peak at 𝑧∼1.5 both in pure density and pure luminosity evolution mode which is followed by the decrease in space density and luminosity out to a z∼6.
