摘要: The distribution of radio to optical fluxes in AGN is bimodal. physical origin for this bimodality not understood. In Letter I describe observational evidence, based on the Boroson & Green PG quasar sample, that loudness strongly related black hole mass (M_BH). Nearly all quasars with M_BH>10^9M_sun are loud, while M_BH<3x10^8M_sun practically quiet. This result consistent dependence host galaxy morphology loudness. There no simple explanation result, but it may provide a clue how jets formed near massive holes. loudness--black relationship suggests properties various types be largely set by three basic parameters, M_BH, L/L_Eddington, and inclination angle.
