| Description | We propose 15.6 hours of Herschel time to secure high quality data,over the entire 70-500 micron range, for a group of 27 local, luminous active galactic nuclei (the QUEST AGN sample). The sources represent well the optically selected PG-QSO sample with redshifts up to z=0.3, and have been investigated, in great detail, in almost all other wavelength bands. The new far infrared (FIR) data set will be ideal to study various fundamental questions related to the connection and co-evolution of AGN and their host galaxies. Our previous Spitzer/IRS work on the sample has already revealed a clear relationship between the total AGN luminosity and the star formation rate (SFR) in their hosts. However, the previously undetected FIR sources may be situated in red-and-dead hosts and the Herschel observations can find these objects and allow a direct comparison of their AGN properties, like black hole (BH) mass and accretion rate, with those of the sources with high SFR. The observations will also provide unique information about the intrinsic infrared AGN spectrum with consequences to dust properties and distribution in such objects. Our sample is a needed ingredient in any Herschel-based studies that combine FIR-selected (IRAS, Spitzer, Herschel) and optically selected samples with their different biases. Its later comparison with similar high redshift observations will provide invaluable information about the cosmological evolution of AGN and star forming galaxies. |

| 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 µm range, bridging the gap between earlier infrared space missions and groundbased facilities. |
