| Abstract | With this proposal we will construct a comprehensive library of X-ray to mid-IRradio-loud quasar spectral energy distributions for a single epoch ( z=1 ),using a sample that is precisely matched to a companion sample of radio quietquasars. In doing so, we will decouple luminosity effects from evolutionaryeffects and so determine the amount of radiation that is absorbed andreprocessed by the torus, and how this depends on luminosity. The SED librarywill represent a fundamental resource for future investigations of the accretionhistory of massive black holes, and will allow us to reconcile conflictingresults on AGN obscuration at different wavelengths and to answer key questionsabout the radio-loud/radio-quiet dichotomy. |

| Mission Description | The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis. |
