Properties of the Galactic population of cataclysmic variables in hard X-rays
2008
Astronomy and Astrophysics
We measure the spatial distribution and hard X-ray luminosity function of cataclysmic variables (CVs) using the INTEGRAL all-sky survey in the 17-60 keV energy band. The vast majority of the INTEGRAL detected CVs are intermediate polars with luminosities in the range 10^32-10^34 erg/sec. The scale height of the Galactic disk population of CVs is found to be 130+90-50 pc. The CV luminosity function measured with INTEGRAL in hard X-rays is compatible with that previously determined at lower
