Scientific paper

Despite extensive searches over a wide wavelength range, the population of heavily obscured Compton-thick AGN still remains elusive. In particular, at high redshifts and luminosities only about a few Compton-thick sources have been discovered. We propose a pilot program of moderately deep XMM exposures (80 ksec each) to observe 3 luminous QSOs at z~1 which are likely to suffer from heavy obscuration. The targets have been selected from the SDSS DR5 based on their strong [NeV]3427 emission. The proposed observations will determine their obscuration revealing if they are indeed Compton-thick, and will possibly serve as a pathfinder for larger programs.
