We propose to observe, for 20 ks each, 4 bright (F{2-10)>2x10^{-11} erg/cm2/s)and luminous (L(2-10}>10^{44} erg/s) radio-quiet AGN from the Grossan HEAO1catalog. The sources have been selected among those not yet observed by imaginghard X-ray instruments, but that were bright enough in ROSAT PSPC to makeidentification secure. The observation of these bright and luminous objects willsubstantially contribute to fill our knowledge gap on the spectral properties ofluminous Seyferts, which are still poorly known. The main aim of the proposalis, by comparison with less luminous sources to search for luminosity-dependentspectral properties, and in particular to test the so-called X-ray Baldwineffect, i.e. the diminution of the iron line EW with luminosity.

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.
