cds-question@unistra.frgalaxiescatalogsactive-galactic-nucleiredshiftedvisible-astronomyh-beta-photometryWe use CANDELS imaging, 3D-HST spectroscopy, and Chandra X-ray data to investigate if active galactic nuclei (AGNs) are preferentially fueled by violent disk instabilities funneling gas into galaxy centers at 1.3<z<2.4. We select galaxies undergoing gravitational instabilities using the number of clumps and degree of patchiness as proxies. The CANDELS visual classification system is used to identify 44 clumpy disk galaxies, along with mass-matched comparison samples of smooth and intermediate morphology galaxies. We note that despite being mass-matched and having similar star formation rates, the smoother galaxies tend to be smaller disks with more prominent bulges compared to the clumpy galaxies. The lack of smooth extended disks is probably a general feature of the z~2 galaxy population, and means we cannot directly compare with the clumpy and smooth extended disks observed at lower redshift. We find that z~2 clumpy galaxies have slightly enhanced AGN fractions selected by integrated line ratios (in the mass-excitation method), but the spatially resolved line ratios indicate this is likely due to extended phenomena rather than nuclear AGNs. Meanwhile, the X-ray data show that clumpy, smooth, and intermediate galaxies have nearly indistinguishable AGN fractions derived from both individual detections and stacked non-detections. The data demonstrate that AGN fueling modes at z~1.85 - whether violent disk instabilities or secular processes - are as efficient in smooth galaxies as they are in clumpy galaxies.2014ApJ...793..101Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/793/101CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/261 : GOODS initial results (Giavalisco+, 2004)J/ApJS/195/10 : The CDF-S survey: 4Ms source catalogs (Xue+, 2011)J/ApJS/203/24 : Structural parameters of galaxies in CANDELSJ/ApJS/207/24 : GOODS-S CANDELS multiwavelength catalog (Guo+, 2013)J/ApJS/214/24 : 3D-HST+CANDELS catalog (Skelton+, 2014)J/ApJ/801/97 : GOODS-S + UDS stellar mass catalogs from CANDELShttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/793/101https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/793/101http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/793/101https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/793/101https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/793/101http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/793/101GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/793/101/table1 (Galaxy Properties)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/793/101/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/793/101/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/793/101/table1?GETtext/xml+votable180.050000true53.06727982-27.862987520.0055555555555555566/35935https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/793/101?format=asciiOpticaldefaultJ/ApJ/793/101/table1Galaxy PropertiesrecnoRecord number assigned by the VizieR team.
