Age indicators H_δ − D_n(4000) plots for our sample. The triangles and the squares denote the obscured and the unobscured AGN respectively. The colour-coded key gives the value of the (a) intrinsic AGN column density. The dotted lines gives the contours that include 68% and 99% of the LEGA-C galaxy population (b) stellar mass, (c) specific SFR, (d) normalised SFR, (e) Eddington ratio, and (f) stellar velocity dispersion. The obscured and unobscured AGN samples have not been corrected for differences in their luminosity and redshift distribution.
