| Abstract | GT- It is proposed to measure the X-ray spectrum of a number of quasars withredshift ~3 in order to probe quasar emission to rest energies as high as 50keV, search for evolution in quasar spectral emission commensurate with theknown evolution in luminosity, and search for environmental and otherdifferences between radio quiet and radio loud quasars. The observation ofSP891107+487 is split into two self contained segments of 45ks and 35ks inorder to fit within the maximum contiguous observing slot. They should beobserved as close together in time as possible (contiguous desirable) to samplethe same intensity state of the source. Some observations use Grism andnon-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. |
