cds-question@unistra.fractive-galactic-nucleiredshiftedx-ray-sourcesWe present results from a statistical analysis of 173 bright radio-quiet active galactic nuclei (AGNs) selected from the Chandra Deep Field-North and Chandra Deep Field-South surveys (hereafter, CDFs) in the redshift range of 0.1<~<~4. We find that the X-ray power-law photon index ({Gamma}) of radio-quiet AGNs is correlated with their 2-10keV rest-frame X-ray luminosity (LX) at the >99.5% confidence level in two redshift bins: 0.3~<z~<0.96, and 1.5~<z~<3.3 and is slightly less significant in the redshift bin 0.96~<z~<1.5.2008AJ....135.1505Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/135/1505CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/126/539 : The Chandra Deep Fields North and South (Alexander+, 2003)J/ApJS/155/73 : Photometric redshifts of X-ray sources in CDF-S (Zheng+, 2004)J/ApJ/640/167 : AGNs and ULIRGs in the CDF-South (Alonso-Herrero+, 2006)J/A+A/497/81 : Variability-selected AGN in CDFS (Boutsia+, 2009)J/A+A/507/1277 : Multiwavelength photometry of CDFS X-ray sources (Brusa+ 2009)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/135/1505https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/135/1505http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/135/1505https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/135/1505https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/135/1505http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/135/1505GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/135/1505/table2 (Properties of our sample of RQ AGNs selected from the Chandra Deep Field Surveys)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/135/1505/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/135/1505/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/135/1505/table2?GETtext/xml+votable180.050000true188.838833362.27447220.0055555555555555566/11230 11252 35935https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/135/1505?format=asciiX-rayOpticaldefaultJ/AJ/135/1505/table2Properties of our sample of RQ AGNs selected from the Chandra Deep Field SurveysSimbadNameSimbad column added by the CDSmeta.idcharn_CXO[OR] Type of fit (1)meta.notecharrecnoRecord number assigned by the VizieR team.
