Relative presence of the different quenching mechanisms analyzed in this work. Top panel: All values given relative to the subset of quenched galaxies (sSFR < 10⁻¹¹ yr⁻¹) with low gas fractions (M_HI/M_★ < 0.2). Bottom panel: Corresponding mechanisms identified in the star-forming subsample. Galaxies that do not meet the classification criteria are labeled “inconclusive”. The count of galaxies undergoing secular evolution (hatched bars in the bottom panel) is complemented by objects with symmetric gaseous kinematics but insufficient S/N in the stellar maps to classify that component as symmetric.
