2004A&A...423..469S Statistical properties of local active galactic nuclei inferred from the RXTE 3-20 keV all-sky survey S. Yu. Sazonov and M. G. Revnivtsev Received 27 January 2004 / Accepted 16 April 2004 We compiled a sample of 95 AGNs serendipitously detected in the 3-20 keV band at Galactic latitude |b|>10^deg^ during the RXTE slew survey (XSS, Revnivtsev et al. 2004), and utilize it to study the statistical properties of the local population of AGNs, including the X-ray luminosity function and absorption distribution. We find that among low X-ray luminosity (L_3-20_< 10^43.5^ erg s^-1^) AGNs, the ratio of absorbed (characterized by intrinsic absorption in the range 10^22^ cm^-2^<N_H_<10^24^ cm^-2^) and unabsorbed (N_H_<10^22^ cm^-2^) objects is 2:1, while this ratio drops to less than 1:5 for higher luminosity AGNs. The summed X-ray output of AGNs with L_3-20_>10^41^ erg s^-1^ estimated here is smaller than the earlier estimated total X-ray volume emissivity in the local Universe, suggesting that a comparable X-ray flux may be produced together by lower luminosity AGNs, non-active galaxies and clusters of galaxies. Finally, we present a sample of 35 AGN candidates, composed of unidentified XSS sources. Keywords: galaxies: Seyfert, X-rays: general, galaxies: quasars: general
