| Description | A short XMM-Newton observation of the luminous narrow line QSO PG1211+143 has provided perhaps the best evidence yet for a massive and energetic outflow in an AGN, a property that may be characteristic of Eddington-limited accretion. In addition, the unusually strong soft X-ray spectrum of PG1211+143 has been a focus of recent attempts to understand the origin of the soft excess in AGN. We request an extended study of PG1211+143 in AO6, to obtain improved quality EPIC and RGS spectra, with better coverage of the anticipated spectral variability timescales, to allow the X-ray spectrum to be de-convolved and the ionisation structure and dynamics of the outflow better understood. |

| 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. |
