| Description |
We propose Herschel observations of a sample of 176 AGN selected over a narrow redshift range (0.9<z<1.1) but spanning 5 magnitudes in optical luminosity. This selection allows us to decouple luminosity dependent effects from evolutionary effects in a sample selected close to the peak of AGN activity. Combined with our existing multiwavelength dataset (Spitzer, XMM-Newton, SWIFT, UKIRT.) the Herschel observations will provide a benchmark for all future high-redshift AGN studies. We have three primary science goals: (1) to determine the evolutionary status of the AGN by measuring their stellar masses, black-hole masses and star-formation rates, (2) to determine how the spectral energy distributions of the AGN vary as a function of luminosity, and (3) to determine the evolutionary status of the .galaxy clusters. known to be forming around the AGN. Theaims of this proposal can only be achieved with pointed observations made with the Herschel Space Observatory. |
