| Description | We propose to observe with XMM-Newton, for a total of 310 ks, the Bian et al. (2006) subsample of type 2 AGN at zvirgul0.3-0.4 for which they could estimate lambda=L_{bol}/L_{Edd}, with the aim to: a) Confirm, by means of a more direct estimate of L_{bol} based on X-rays rather than on L[O III], as Bian et al. did, that the sources have mostly lambdavirgul1, and check whether the super-Eddington sources did really exist or are an artifact due to the uncertainties in the L[O III]-L_{bol} relationship. b) Determine the fraction of Compton-thick AGN at zvirgul0.3-0.4, high Eddington ratios, and high luminosities, to be compared with measurements based on local, low luminosities samples to search for correlation between obscuration and both the Eddington ratio and the luminosity. |

| 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. |
