Left: histogram of integrated 1.4 GHz radio luminosity expressed in Eddington units, estimated using BH masses determined via direct methods. The position of the antimode at log L_1.4 GHz/L_Edd = −8.6, identified using the locmodes function, is indicated by a black vertical line. Right: Same as the left panel, but using BH masses estimated indirectly from the M_BH − σ_* relation of Graham & Scott (2013). The vertical line indicates the position of the antimode at log L_1.4 GHz/L_Edd = −8.6.
