Abstract: Three lines of evidence connect AGN to the presence of supermassive black holes in galaxy nuclei (in addition to Fe K α profiles). One is direct measurement of the motions of stars or gas in the nuclear region. A second rests on the plausible identification of the mass density in (largely quiescent) black holes in the local Universe with that inferred from quasars in the distant Universe. A third results from direct comparison of black hole mass determination for AGN from the velocity dispersion or luminosity of the host bulge with that derived from emission line reverberation mapping. The first method provides direct demonstration; the other two are strongly consistent.
