Characterization of hard X-ray selected CV candidates

About 20% of hard Xray galactic sources detected in the INTEGRAL and Swiftsurveys are accreting white dwarf binaries (CVs). The majority harbours magneticprimaries, which are disputed to be important contributors to the galacticpopulation of lowluminosity Xray sources. Optical followups allow to selectgood candidates, but a secure identification resides in the Xrays. XMMNewtonhas shown the unique potential to detect Xray spin pulses and caracterize thespectral properties with high S/N data. We here propose to continue anidentification programme with 7 new candidates in order to obtain a true censusof hard Xray CVs, in view of the accurate distances to be provided by Gaia truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
