Description We propose to exploit the superior sensitivity and spectral resolution of the instruments onboard XMM to perform a detailed study of a sizeable sample of radio-quiet quasars at redshifts (z = 1-2) where the effects of cosmological evolution become extremely important. More specifically we want to explore the photon index -- lron line intensity -- luminosity parameter space in a region unexplored by the previous missions. The proposed observations will allow to put strong constraints on the evolution of the X-ray spectral slopes and iron line intensity and ionization state.

Mission Description The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's 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 Earth's 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.
