To date RX J1343.4+0001 (F(0.5-10) virgul 2 x 10e(-13) erg/cm2/s) appears the bestcandidate to unambiguously confirm the existence of radio-quiet X-ray obscuredtype II QSOs at high redshifts. By the 35 ks observation proposed here we willbe able to definitively disentangle between the two hypothesis suggested on thebasis of previous less sensitive ROSAT and ASCA measurements, i.e. a truly flatspectrum (very unusual for a radio-quiet QSO) or a highly absorbed object. Themain goal of this proposal is to obtain the first high-quality X-ray spectrum ofa member of this elusive class of high luminosity obscured sources whoseexistence is required in the synthesis models of the cosmic X-ray background.

Mission Description
The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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.
