cds-question@unistra.frquasarsactive-galactic-nucleix-ray-sourcesultraviolet-astronomyThe observed relation between the X-ray radiation from active galactic nuclei, originating in the corona, and the optical/UV radiation from the disk is usually described by the anticorrelation between the UV to X-ray slope {alpha}_ox_ and the UV luminosity. Many factors can affect this relation, including: i) enhanced X-ray emission associated with the jets of radio-loud AGNs, ii) X-ray absorption associated with the UV broad absorption line (BAL) outflows, iii) other X-ray absorption not associated with BALs, iv) intrinsic X-ray weakness, v) UV and X-ray variability, and non-simultaneity of UV and X-ray observations. The separation of these effects provides information about the intrinsic {alpha}_ox_-L_UV_ relation and its dispersion, constraining models of disk-corona coupling. We use simultaneous UV/X-ray observations to remove the influence of non-simultaneous measurements from the {alpha}_ox_-L_UV_ relation.2010A&A...519A..17Vhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/519/A17CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toIX/41 : XMM-Newton Serendipitous Source Catalogue 2XMMi-DR3 (XMM-SSC, 2010)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/519/A17https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/519/A17http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/519/A17https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/519/A17https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/519/A17http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/519/A17GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/519/A17/table1 (Sources studied in the paper)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/519/A17/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/519/A17/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/519/A17/table1?GETtext/xml+votable180.050000true9.8429170.99750.0055555555555555565/6814 6/4245 4859 4924 4967 4976 5112 5116 5244 5305 5420 5437 5469 5482 5486 5560 5576 5630 5701 5715 5733 5795 5816 5862 5952 5970 6021 6033 6035 6062 6069 6075 6252 6458 6498 6574 6977 7178 7241 7266 7273 7281 7424 7522 8195 8324 9077 9168 9181 9353 9468 9512 9632 9895 9959 10306 10312 10399 10401 10549 10578 10598 10601 10604 10657 10664 10694 10709 10769 10896 10938 10969 11204 11206 11252-11253 11337 11377 11392 11424 11591 11596 11787 11790 11806 11856 11925 11931-11932 11936 17493 17497 17745 17752 17754 17761 17816 17840 18003 18032 18071 18385 18388 18780 18782 18800 19033 19036 19097 19416 23102 23191 23208-23209 25965 25982 26019 26022 26091 26175 26188-26189 26209 26292 26298 26370 26407 27051 27247 27343 27383 27423 27428 27440 27537 27580 27617 27715 27719-27720 27722 27728 27742 27767 27773 27862 27907 28184 28589 28632 31396 31398 31652 32486 36785 36861https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/519/A17?format=asciiX-rayUVdefaultJ/A+A/519/A17/table1Sources studied in the paperrecnoRecord number assigned by the VizieR team.
