| Abstract | XMM may prove to be the premier instrument for studying Fe K lines in quasars. We propose a 60 ksec XMM observation of the z=1.265 quasar 4C 06.41 to study the Fe K-alpha emission line detected with ASCA as well as other features of reflection and intrinsic absorption. 4C 06.41 is an X-ray bright radio loud quasar and is one of the few high-z quasars to possess a significant Fe K-alpha line. Since Fe K lines in high-z quasars are so rare, this makes 4C 06.41 an excellent target to help expand our knowledge of quasars in the high-z regime. XMM is needed to improve upon the signal-to-noise available from the archival ASCA spectrum in order to make useful measurements of the line and continuum. |

| 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. |
