| Abstract | GT- Below 2 keV, the x-ray spectra of many AGNs deviates from a simple power lawcontinuum absorbed by Galactic material. In particular, a large fraction of type1 active galactic nuclei show K-shells absorption edges of warm oxygencharacteristic of optically thin, photoionized material along the line of sightto the central engine, the so-called warm absorber. The high spectral resolutionof RGS combined with the possibility of long uninterrupted observations will beused to study the spectral structure and time variability of the warm absorberand to derive further constraints on the distribution of the photoionized plasmasurrounding the AGNs central source. |

| 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. |
