Description 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 a few Compton-thick objects have been discovered. We propose a pilot program of moderately deep XMM exposures (40 to 80 ksec each) to observe 3 luminous QSOs at zvirgul1, which is the epoch where the bulk of the ..missing. X-ray background is expected to be produced. These QSOs are likely to suffer from heavy obscuration. The targets have been selected from the SDSS DR5 based on their strong [NeV]3427A emission. The proposed observations will unambiguously determine their obscuration degree.

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.
