Description | We propose here to perform X-ray spectroscopy of a sample of 13 optically-bright AGN with an Eddington ratio virgul1 in a restricted range of redshift (z virgul 0.5-0.7), SMBH mass (virgul1e8 Msun) and bolometric luminosity (virgul1e46 erg-s). Our program is designed to significantly improve our understanding of the X-ray spectral properties of highly-accreting AGN. Specifically, we aim at providing a reference dataset for shedding definitive light on the hotly-debated, recently-questioned correlations Edd_ratio vs. Gamma, and Edd_ratio vs. X-ray bolometric correction. The current lack of data at Edd_ratio >virgul 1 indeed hampers firm conclusions on the strength of these relations. |

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. |
