We propose to observe the 1-25 keV (rest-frame) SED of 6 active galactic nucleifrom a unique zvirgul1.55 VLT/X-shooter sample. Our soon-to-be published observationsof the sources show that their 1200-9800A rest-frame SED can be fitted,accurately, by thin accretion disk spectra, which allows us to measure the BHspin parameter, a*, in this sample. This XMM proposal is a pilot study aimed atthe understanding of the X-ray properties of two sub-groups of this sample: fourobjects with the largest spin (a* = 0.998) and four with the lowest spin (a* <0.3). The data will be used to look for high and low spin indicators in theX-ray SED of luminous AGNs, in particular the 2-10 keV slope, alpha-OX and,perhaps, by stacking analysis, some information on K-alpha.

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.
