Perola, G. Matt Topic: 6 Session: oral Abstract: The fraction of Compton-thin AGN appears observationally to be anticorrelated to their X-ray luminosity. The molecular torus seems not to conform to this new constraint. We present a model in which the Compton-thin absorption is due to the molecular gas in the host galaxy disk. The gravitational effects of the black hole on the disk shape then leads naturally to the observed anticorrelation.
