We selected all radio-quiet active galactic nuclei (AGN) in the latest release of the Sloan Digital Sky Survey quasar catalogue, with redshift in the range 0.560.73.

Abstract
We selected all radio-quiet active galactic nuclei (AGN) in the latest release of the Sloan Digital Sky Survey quasar catalogue, with redshift in the range 0.560.73. About 4000 (similar to 80 per cent) of these have been detected in all four infrared bands of Wide-field Infrared Survey Explorer (WISE). This is the largest sample suitable to study the disctorus connection. We find that the torus reprocesses on average similar to 1/31/2 of the accretion disc luminosity
