Abstract | From INTEGRAL and Swift surveys a significant fraction of hard X-ray sourceswere found to be magnetic Cataclysmic Variables(CVs) of the Intermediate Polar(IP) type. Optical follow-ups of ~100 unidentified INTEGRAL sources show that~15% of the new detections have magnetic CV-like spectra. A timely question iswhether IPs provide an important contribution to the hard X-ray sky and hencestill represent a hidden population of galactic X-ray sources. We propose tocontinue our identification programme of newly discovered CVs, which are strongmagnetic candidates. The detection of X-ray pulses and the study of their broadband X-ray spectra will allow a firm identification of their nature and willprovide further insights in physics of this emerging class of accreting compact 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. |
