Description GT - The XMM observation of this Seyfert galaxy will be used to separate and characterise the various components in its X-ray spectrum and to study their behaviour over time. This object has shown evidence for absorption by ionised oxygen, which suggests the presence of a dusty warm absorber, and for significant variability. We will derive physical parameters (ionisation stages, densities, gas velocities, etc.) over time, and use RGS to search for emission features (particularly OVIII Lyman alpha) from the warm absorber.

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.
