Abstract

It has been recently proposed that the broad-line region in active galactic nuclei originates from dusty clouds driven from the accretion disc by radiation pressure, at a distance from the black hole where the disc is cooler than the dust sublimation temperature. We test this scenario by checking the consistency of independent broad-line region and accretion disc reverberation measurements, for a sample of 11 well-studied active galactic nuclei. We show that independent disc and broad-line region reverberation mapping measurements are compatible with a universal disc temperature at the H beta radius of T(R-H beta) approximate to 1670 +/- 231 K which is close to typical dust sublimation temperatures.
