Title:	The AGN torus: the IR sore thumb - introducing CLiF and K-Bump AGN
Topic:	Discoveries
Abstract:	The nature and origin of the dusty obscuring torus surrounding active nuclei - whether it is inflowing, outflowing, its relation to star formation - are important for our understanding of the evolution of Active Galactic Nuclei (AGN), and how they affect their environment (‘feedback’). At IR (WISE) wavelengths, the spectral energy distributions (SEDs) of AGN are dominated by thermal emission from dust in the torus. I introduce both CLiF and K-bump AGN, two new classes of AGN which are laboratories for testing torus models of AGN. CLiF AGN have a rich spectrum of forbidden high ionization lines (e.g. [FeVII], [FeX] and [NeV]), as well as show a clear mis-match between the optical and IR parts of their SEDs. K-bump AGN show evidence for isolated maximally hot dust at the 2MASS-WISE wavelength boundary. We suggest that these objects are viewed at a specific angle which provides a maximal view of the far wall of the torus.
