| Abstract | The ROSAT Ultradeep HRI Survey in the Lockman Hole has resolved 70-80 percent ofthe soft X-ray background (XRB) into discrete sources, most of which have beenidentified as AGN with the Keck including some type 2 AGN, which are thought tobe responsible for the hard spectrum of the XRB. The space density of AGNapparently does not decline at z>3 like seen in optical and radio surveys.However, the sample statistics of a single deep fied is rather limited. The nextgeneration X-ray deep surveys ideally combine XMM and AXAF observations of thesame field. Here we propose a 150 ksec XMM survey of the Lynx.3A field, whichwill be observed for 190 ksec with AXAF. We will thus double the X-ray deepsurvey area and will obtain high quality XMM spectra of 25 and hardness ratios for 100 objects. |

| 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. |
