Characterization of hard X-ray selected binaries:a census of magnetic CVs

A large number of hard Xray galactic sources are detected in the INTEGRAL andSwift surveys, among them virgul20percent are accreting white dwarf (WD) binaries(CVs). The majority harbours asynchronously rotating magnetic primaries, whichnowdays are disputed to be the dominant galactic population of lowluminosityXray sources. While optical followups allow to find magnetic CV candidates,asecure identification of their true nature resides in the Xrays. WithXMMNewton 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 firstvolumelimited sample of hard Xray CVs. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
