| Description | GT- An observation of a bright nearby radio-quiet quasar (PG1211+143) is proposed for XMM GT time. By studying the Fe line profiles (with EPIC) in these objects, the physics of the accretion disk, and the strong gravity associated with the supermassive black hole, can be studied. In addition, soft X-ray excesses, also perhaps associated with emission or reprocessing from the accretion disk, can be explored. In this respect, an important aim will be to obtain a high quality RGS spectrum of a soft X-ray bright, luminous AGN, as a diagnostic of the primary emitting region. Evidence for reprocessing in the RGS band, either through ionised disk reflection or through a .warm. absorber will also be important. |

| 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. |
