Description At present, though we suspect that highly obscured AGN may play a major role in the infrared background and the evolution of galaxies, we have a poor empirical measure of the intrinsic spectral energy distributions of dust-obscured AGN. It is presumed that the obscured X-ray and UV photons are re-emitted in the infrared, but with what SED shape? How important is very hot dust versus very cool dust? What does the SED say about the circumnuclear structure, compared to unobscured AGN? To address these questions, we propose PACS-SPIRE 60-500 micron imaging of five nearby Compton-thick AGN, which we will combine with an additional four targets already in the Herschel archive. We will combine this dataset with our existing dataset from Spitzer to create high--quality 5--500 micron SEDs. This will help us understand how AGN obscuration works in the nearby universe, and will provide templates to apply to higher redshift to better understand the cosmological importance of buried accretion and its contribution to the infrared and X-ray backgrounds.

Mission Description Herschel was launched on 14 May 2009! It is the fourth 'cornerstone' mission in the ESA science programme. With a 3.5 m Cassegrain telescope it is the largest space telescope ever launched. It is performing photometry and spectroscopy in approximately the 55-671 ┬Ám range, bridging the gap between earlier infrared space missions and groundbased facilities.
