| Description | GT- Deep XMM pointings are proposed to measure the X-ray spectrum of faint X-ray emitting galaxies and so determine whether they are a major contributor to the X-ray background. These data will also be important for constraining the evolution of these galaxies, and for understanding the evolution of the low-luminosity end of the quasar luminosity function. The same data will also be used to measure the distribution of multiwavelength spectral parameters of quasars, and to study faint clusters of galaxies. Observations of two targets are each split into three segments. It is desirable that all segments are observed at a similar roll angle. The observations use non-default OM windows. |

| 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. |
