Description The number of hard X-ray emitting Cataclysmic Variables (CVs) has been boosted in the recent years, unveiling the dominance of asynchronously rotating, magnetic accreting white dwarf primaries - the Intermediate Polars. These systems are disputed to be important contributors to the galactic population of low-luminosity X-ray sources. We have been carrying out a systematic identification programme of new optically discovered hard X-ray CV candidates with the unique potential of XMM-Newton to securely assess their purported magnetic nature by detecting X-ray spin pulses and characterizing their spectral properties. We aim at obtaining a CV flux-limited sample with Gaia distances finally making statistical studies possible and uncover the true population of low luminosity sources.

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.
