Description We propose to obtain XMM-Newton spectra for the only three QSO2 candidates found in the completely identified ROSAT North Ecliptic Pole survey. These objects show optical narrow high-ionization lines and very high X-ray luminosities. Obscured QSO2 are a key ingredient in models of the diffuse X-ray background, but they are not found in large number as expected. The spectra that we propose to obtain will confirm the classification as obscured QSO2 if we detect absorption also in the X-ray band. It will be possible to probe the internal structure of the emitting region, and detect the presence of absorbing or reflecting material. The complete identification status of the survey will allow us for the first time to compute QSO2 spatial density in the soft X-ray sky.

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.
