1.4 GHz AGN luminosity function of the full VLA-COSMOS 3 GHz Large Project sample with COSMOS2015 counterparts out to z ∼ 6. The AGN and total luminosity functions are shown with black and red circles, respectively. Solid and dashed black lines show the fit of analytic local AGN luminosity function in PDE and PLE models, respectively, with shaded areas indicating 1σ confidence range. The black and red vertical dashed lines show the luminosity corresponding to the 5σ sensitivity at z_min and z_max of the redshift bin, respectively. Results from the literature are also shown, as detailed in the legend.
