The nature of hard X-ray selected CV candidates

The number of hard Xray emitting Cataclysmic Variables (CVs) has been boostedin the recent years, unveiling the dominance of asynchronously rotating,magnetic accreting white dwarf primaries the Intermediate Polars. Thesesystems are disputed to be important contributors to the galactic population oflowluminosity Xray sources. We have been carrying out a systematicidentification programme of new optically discovered hard Xray CV candidateswith the unique potential of XMMNewton to securely assess their purportedmagnetic nature by detecting Xray spin pulses and characterizing their spectralproperties. We aim at obtaining a CV fluxlimited sample with Gaia distancesfinally making statistical studies possible and uncover the true population of low luminosity sources. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
