cds-question@unistra.fractive-galactic-nucleix-ray-sourcesWe present the results of a new spectroscopic study of Fe K-band absorption in active galactic nuclei (AGN). Using data obtained from the Suzaku public archive we have performed a statistically driven blind search for FeXXV He{alpha} and/or FeXXVI Ly{alpha} absorption lines in a large sample of 51 Type 1.0-1.9 AGN. Through extensive Monte Carlo simulations we find that statistically significant absorption is detected at E>~6.7keV in 20/51 sources at the P_MC_>=95% level, which corresponds to ~40% of the total sample. In all cases, individual absorption lines are detected independently and simultaneously amongst the two (or three) available X-ray imaging spectrometer detectors, which confirms the robustness of the line detections. The most frequently observed outflow phenomenology consists of two discrete absorption troughs corresponding to FeXXV He{alpha} and FeXXVI Ly{alpha} at a common velocity shift. From xstar fitting the mean column density and ionization parameter for the FeK absorption components are log(N_H_/cm^2^)~23 and log({xi}/erg/cm/s)~4.5, respectively. Measured outflow velocities span a continuous range from <1500km/s up to ~100000km/s, with mean and median values of ~0.1c and ~0.056c, respectively. The results of this work are consistent with those recently obtained using XMM-Newton and independently provides strong evidence for the existence of very highly ionized circumnuclear material in a significant fraction of both radio-quiet and radio-loud AGN in the local universe.2013MNRAS.430...60Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/430/60CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/430/60https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/430/60http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/430/60https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/430/60https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/430/60http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/430/60GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/430/60/tablea1 (Summary of observation parameters)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/430/60/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/430/60/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/430/60/tablea1?GETtext/xml+votable180.050000true66.5029792-57.20047060.0055555555555555566/1263 1405 4439 5355 6977 7246 7309 7642 8299 8922 10912 10927 11898 12002 12025 13414 14858 15433 15481 16184 16301 16671 17075 18524 18683 19283 19797 19883 21245 22890 23323 25907 26148 27862 28517 28535 29398 33930 34065 34531 34881 38268 38653 40410 40838 41435 43806 43877 45735 46615 49042https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/430/60?format=asciiX-raydefaultJ/MNRAS/430/60/tablea1Summary of observation parametersSimbadNameSimbad column added by the CDSmeta.idcharrecnoRecord number assigned by the VizieR team.
