| Abstract | A large number of hard X-ray galactic sources are detected in the INTEGRAL andSwift surveys, among them ~20percent are accreting white dwarf (WD) binaries(CVs). The majority harbours asynchronously rotating magnetic primaries, whichnowdays are disputed to be the dominant galactic population of low-luminosityX-ray sources. While optical follow-ups allow to find magnetic CV candidates,asecure identification of their true nature resides in the X-rays. WithXMM-Newton we could successfully prove or disprove the magnetic nature for 24sources. We here propose to continue our identification programme with 8 newcandidates with the ultimate goal to obtain a true census of the firstvolume-limited sample of hard X-ray CVs. |

| 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. |
