The properties of dusty tori in Active Galactic Nuclei (AGN) can be derived from the comparison of their observed Spectral Energy Distributions (SEDs) and models describing the dust in the pc-to-kpc range from the nucleus. The SEDs of hundreds of AGN, grouped in complete flux-limited samples, expand from the UV to the mid-IR. The torus model is that presented by Fritz, Franceschini and Hatziminaoglou (2006). Models with low equatorial optical depth, tau_9.7, are introduced for the first time and the results are compared with those derived using the “traditional” (tau_9.7 > 1.0) models. Properties such as the size of the torus, the mass of dust and the infrared (IR) luminosity are derived and the hypothesis of a receding torus model (i.e. luminosity-dependent torus geometry) is checked. Objects with 70 micron detections are studied separately, as they provide useful information on the star formation activity. The relative AGN and starburst contribution to the IR luminosity is discussed. (Host: Kambiz Fathi)
