Abstract We propose XMM EPIC spectroscopy of the five most X-ray luminous radio-quietQSOs found in the ROSAT Bright Survey (RBS). The RBS contains the brightestX-ray sources in the sky. Hence, the sample marks the high end of the local ( z<0.5 ) QSO luminosity function. Self-consistent disk reflection models predictstrong, neutral Fe lines emission in low X-ray luminosity AGN, while high X-rayluminous QSOs are expected to show weaker, high ionization Fe lines. A furtherincrease in X-ray luminosity elimates the Fe line emission (X-ray Baldwineffect). Observational evidence for these predictions are so far poorlyestablished and controversally discussed.

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.
