| Abstract | SA 57 is one of the best studied sky areas at all wavelengths.We propose a 80 ksXMM observations of this field, which matches the XMM field of view, to detectAGNs down to ~ 0.5, 2 x 10^-15 cgs respectively in the 0.5-2, 2-10 keV bands.The aim of the project is: i) to detect new absorbed QSOs/AGNs which possiblyescaped optical selection; ii) to perform a comparative study of the optical andX-ray properties of the AGNs in the field; iii) to estimate the evolution of thedifferent populations of objects and their contribution to the cosmic X-raybackground. |

| 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. |
