Scientific paper
We propose to observe with XMM-Newton, for a total of 310 ks, 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}, 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 lambda 1, 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 z 0.3-0.4, 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.
