| Abstract | Recent optical and mid-IR constraints suggest that the putative torussurrounding Active Galactic Nuclei (AGN) may recede with increasing AGN power.Such a result, if true, has important ramifications on AGN unification and theevolution of supermassive black holes (SMBHs). Surprisingly, the bulk of thehigh-z QSOs used to establish this result lack X-ray constraints. We thereforepropose XMM-Newton observations for this otherwise robustly-studied sample toaddress several remaining questions. The resulting X-ray constraints will becompared to existing OIII and 6um AGN continuum luminosities to yield the mostrobust constraints on potential luminosity dependencies to date. |

| 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. |
