The WISE view of the disc-torus connection in z~0.6 Active Galactic Nuclei

Abstract

We selected all radio-quiet AGN in the latest release of Sloan digital sky survey quasar catalog, with redshift in the range 0.56-0.73. About 4000 (~80%) of these have been detected in all four IR-bands of WISE (Wide-field Infrared Survey Explorer). This is the largest sample suitable to study the disc-torus connection. We find that the torus reprocesses on average ~1/3-1/2 of the accretion disc luminosity.
