| Description | We propose to observe the 1-25 keV (rest-frame) SED of 6 active galactic nuclei from a unique zvirgul1.55 VLT/X-shooter sample. Our soon-to-be published observations of 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 BH spin parameter, a*, in this sample. This XMM proposal is a pilot study aimed at the understanding of the X-ray properties of two sub-groups of this sample: four objects 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 the X-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 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. |
