GT-We propose to observe bright AGN (2-10 keV fluxes around 1E-11 cgs) forwhich X-ray broad-band colours in the 0.1-10 keV band are highlysuggestive of complex absorption. We believe these objects might haveeither both a warm and a cold absorber or a cold absorber which does notfully cover the central source. Our proposed XMM/EPIC spectroscopy aimsat distinguishing between these scenarios and the proper characterisationof these complex absorption features.

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.
