| Abstract | We propose an XMM program to complement a 100 pc resolution HST UV program thatrecently observed 75 of the brightest hard X-ray selected, nearby type 1 BAT AGN(z<0.1), to accurately calibrate the AGN bolometric emission, precisely measurethe Eddington ratio distribution of AGN, and understand the intrinsic UV/X-rayscatter to estimate cosmological parameters. We propose to observe 16 AGNobserved with HST in the past few months with extended nuclear star formation,that have never been observed with XMM. XMM is uniquely sensitive at <1 keV(30-50X) which is critical for accretion disk models. The HST UV capability isdiminishing substantially so it is critical to leverage this once in possiblydecade opportunity for high spatial resolution UV imaging. |

| 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. |
