Description We propose to observe with XMM-Newton the Bian et al. (2006) subsample of type 2 AGN at z=0.3-0.4 for which they could estimate lambda=L_bol-L_Edd, based on the L[O III]. The sources have all high Eddington ratios, and high luminosities. The main aim is to determine the fraction of Compton-thick AGN at z=0.3-0.4, high lambda, high L, 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. This proposal is a continuation of a partially approved AO6 proposal. Three sources were approved in priority B, and two of them have been already observed. Very surprisingly, neither of them were detected, indicating they are extremely X-ray weak.

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.
