Abstract

A distance measurement based on observations of the hot-dust emitting region of the active galaxy NGC 4151 yields a value of 19 megaparsecs, implying a 1.4-fold increase in the dynamical mass of the galaxy’s central black hole and a corresponding correction to emission line reverberation masses of black holes in other active galactic nuclei if calibrated against NGC 4151′s dynamical mass.
