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

| 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. |
