|Title||The nature of the high flux sources seen by the BeppoSAX WFC|
|Author||Dr Elisa Costantini|
|Description||The combination of all data of the BeppoSAX Wide Filed Cameras has revealed the detection of a number of active galactic nuclei and galaxy clusters. Six bright sources, which are confirmations of ROSAT detections, are yet without a determined nature. We propose to carry out short exploratory observations with XMM-Newton of these objects, in order to determine their spectrum and short-term variability and identify possibly interesting features for follow up in future XMM-Newton or Chandra AOs.|

|Mission Description||The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's 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 Earth's 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.
