Median radial profiles equivalent width of Hα (W_Hα) for our sample of galaxies in each quenching stage for non-active (left), weak AGN (middle), and strong AGN (right) classes, normalised by galaxy effective radius R_e (Sect. 4). The shaded regions express the 25th and 75th percentiles of the radial distributions. The blue dash-dotted and dashed horizontal lines display W_Hα = 3 Å and W_Hα = 6 Å thresholds, respectively. The variation in the W_Hα profile suggests an ‘inside-out’ star-formation quenching scenario for our sample of galaxies.
