The specific star formation rate (sSFR, in Gyr^-1) versus the specific black hole accretion rate, sṀ_BH (in Gyr^-1). The galaxies with constrained estimates of both sSFR and sṀ_BH are shown in red, while the arrows indicated upper or lower limits for each or both quantities. sṀ_BH was estimated using the local M_BH–M_Bulge relation (filled red diamonds) or using the N11 offset (empty red squares, see Sect. 6.2.3). The dashed line indicates where the sṀ_BH = sSFR.
