We propose to carry out a snapshot survey of 6 luminous and X-raybright broad line AGN (5 Seyfert 1 and 1 QSO) with very hard X-raycolours and hence, probably strongly absorbed in X-rays. We want tostudy their X-ray spectra (continuum and Fe K lines) to measure thecolumn density and to understand the nature of the X-ray absorber andthe geometry of their central regions. These sources could providebright examples of the optically unobscured but X-ray absorbed AGNthat are routinely found in medium to deep X-ray surveys.

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.
