cds-question@unistra.fractive-galactic-nucleigalaxiesspectroscopyx-ray-sourcesredshiftedsurveysStriking similarities have been seen between accretion signatures of Galactic X-ray binary (XRB) systems and active galactic nuclei (AGNs). XRB spectral states show a V-shaped correlation between X-ray spectral hardness and Eddington ratio as they vary, and some AGN samples reveal a similar trend, implying analogous processes at vastly larger masses and timescales. To further investigate the analogies, we have matched 617 sources from the Chandra Source Catalog (CSC) to Sloan Digital Sky Survey (SDSS) spectroscopy, and uniformly measured both X-ray and optical spectral characteristics across a broad range of AGN and galaxy types. We provide useful tabulations of X-ray spectral slope for broad- and narrow-line AGNs, star-forming and passive galaxies, and composite systems, also updating relationships between optical (H{alpha} and [OIII]) line emission and X-ray luminosity. We further fit broadband spectral energy distributions with a variety of templates to estimate bolometric luminosity. Our results confirm a significant trend in AGNs between X-ray spectral hardness and Eddington ratio expressed in X-ray luminosity, albeit with significant dispersion. The trend is not significant when expressed in the full bolometric or template-estimated AGN luminosity. We also confirm a relationship between the X-ray/optical spectral slope {alpha}_ox_ and Eddington ratio, but it may not follow the trend predicted by analogy with XRB accretion states.2013ApJ...778..188Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/778/188CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/chandra : The Chandra Archive Log (CXC, 1999-2014)IX/45 : The Chandra Source Catalog (CSC), Release 1.1 (Evans+ 2012)VIII/90 : The FIRST Survey Catalog, Version 12Feb16 (Becker+ 2012)II/319 : UKIDSS-DR9 LAS, GCS and DXS Surveys (Lawrence+ 2012)II/311 : WISE All-Sky Data Release (Cutri+ 2012)II/312 : GALEX-DR5 (GR5) sources from AIS and MIS (Bianchi+ 2011)II/294 : The SDSS Photometric Catalog, Release 7 (Adelman-McCarthy+, 2009)VII/233 : The 2MASS Extended sources (IPAC/UMass, 2003-2006)J/ApJ/746/54 : Chandra X-ray observations of SDSS-DR5 QSOs (Gibson+, 2012)J/ApJS/194/45 : QSO properties from SDSS-DR7 (Shen+, 2011)J/MNRAS/405/2243 : GMOS/WIYN spectroscopic catalogue (Trichas+, 2010)J/ApJS/187/64 : The simultaneous optical-to-X-ray SED of AGNs (Grupe+, 2010)J/A+A/512/A34 : XMM-COSMOS Type 1 AGNs (Lusso+, 2010)J/ApJ/705/1336 : X-ray measurements of ChaMP-SDSS galaxies (Constantin+, 2009)J/ApJ/690/644 : Properties of SDSS QSOs in the ChaMP (Green+, 2009)J/ApJ/667/131 : Mass function of active black holes (Greene+, 2007)J/ApJ/642/673 : IR-selected obscured AGN candidates (Polletta+, 2006)J/ApJS/112/315 : Spectroscopic parameters of Seyfert nuclei (Ho+ 1997)http://www.sdss.org/ : SDSS home pagehttp://cxc.cfa.harvard.edu/ : Chandra X-ray observatory (CXC) home pagehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/778/188https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/778/188http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/778/188https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/778/188https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/778/188http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/778/188GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/778/188/table1 (Full z<0.4 spectroscopic Chandra/SDSS catalog)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/778/188/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/778/188/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/778/188/table1?GETtext/xml+votable180.050000true150.415592.43010.0055555555555555565/2629 6/0 4168 4206 4253 4341 4405 4536 4596 4718 4719 4720 4801 4804 4808 4835 4897 4900 4927 5027 5044 5048 5074 5100 5106 5165 5204 5241 5306 5367 5370 5437 5439 5469 5471 5483 5491 5538 5569 5616 5618 5628 5664 5687 5694 5793 5797 5816 5817 5843 5890 5902 5922 5923 5966 5982 5985 5999 6047 6073 6075 6077 6079 6086 6090 6098 6448 6462 6532 6536 6552 6554 6559 6618 6623 6645 7226 7227 7242 7266 7301 7308 7309 7320 7326 7371 7426 7464 7475 7552 8195 8220 8222 8228 8264 8266 8268 8270 8288 8339 8345 8506 8555 8641 8659 8675 8681 8705 8707 8788 8845 8906 8914 8927 8943 8959 8969 8972 8973 8995 9037 9039 9049 9108 9126 9145 9146 9147 9150 9151 9164 9168 9181 9185 9194 9223 9354 9367 9368 9373 9387 9401 9428 9429 9443 9464 9469 9476 9504 9506 9640 9770 9831 9855 9885 9895 9981 9997 10154 10190 10193 10213 10245 10302 10312 10323 10355 10358 10364 10378 10386 10387 10388 10403 10404 10411 10421 10471 10475 10484 10501 10512 10513 10515 10521 10544 10588 10589 10601 10637 10658 10664 10706 10752 10839 10877 10905 10911 10912 10950 10963 10969 10970 10979 10992 11029 11048 11050 11073 11076 11101 11117 11179 11195 11253 11262 11299 11346 11353 11371 11372 11424 11425 11427 11434 11460 11467 11590 11807 12553 17237 17301 17344 17406 17492 17499 17506 17766 17767 17769 17772 17773 17815 17816 17818 17819 17829 18003 18009 18011 18032 18061 18065 18071 18073 18075 18096 18518 18791 18795 18800 18865 18880 19028 19036 19432 19457 19678 22364 23050 23182 23183 25906 25919 25942 25948 25958 25972 26022 26037 26058 26080 26177 26186 26189 26209 26212 26221 26225 26239 26264 26276 26277 26298 26305 26313 26331 26338 26363 26365 26389 26499 26547 26563 26596 26990 27004 27053 27079 27080 27095 27105 27127 27213 27224 27256 27258 27259 27287 27305 27318 27382 27402 27428 27486 27514 27515 27580 27593 27617 27681 27715 27718 27724 27736 27738 27739 27741 27743 27750 27769 27772 27773 27855 27867 27907 27913 27937 27938 27944 27945 28019 28022 28126 28139 28141 28143 28152 28174 28220 28221 28249 28251 28291 28307 28360 28374 28376 28377 28414 28430 28448 28452 28471 28488 28491 28495 28497 28517 28535 28619 28631 28632 31318 31322 31379 31419 32408 32500 32503 36863 49014https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/778/188?format=asciiX-rayOpticaldefaultJ/ApJ/778/188/table1Full z<0.4 spectroscopic Chandra/SDSS catalogE_Gamma[0.01/19] Upper error in Gammastat.error;stat.maxfloatrecnoRecord number assigned by the VizieR team.
