AGN populations. Left: AGN fraction, defined in terms of AGN bolometric luminosity as a function of galaxy mass. We recall that we have assumed an intrinsic active fraction of unity. Solid lines only require L_bol >  10⁴⁴ erg s⁻¹, dotted lines add m444W < 28 (galaxy and AGN combined) and dashed lines are for cLRDs (including the same bolometric and m444W cuts). Right: fraction of AGN-dominated sources at F444W as a function of m277W-m444W. Above m277W-m444W > 1.5 all sources are AGN-dominated.
