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

Among hard Xray galactic sources detected by the INTEGRAL and Swift surveysthose identified as white dwarf binaries (CVs) recently boosted in number. Themajority harbour asynchronously rotating magnetic primaries, suggesting thatthis subclass could be an important constituent of Xray binary populations.XMMNewton demonstrated its unique potential to unambiguously infer their truenature through the detection of Xray spin pulses and the study of broadbandspectra, that proved to be successful for more than 17 targets. We propose tocontinue our identification programme with the ultimate goal to obtain a truecensus of the first volumelimited sample of hard Xray emitting white dwarfsystems. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
