cds-question@unistra.fractive-galactic-nucleiquasarsinfrared-astronomyspectroscopyWe use mid-infrared (MIR) spectroscopy of unobscured active galactic nuclei (AGNs) to reveal their native dusty environments. We concentrate on Seyfert 1 galaxies, observing a sample of 31 with the Infrared Spectrograph aboard the Spitzer Space Telescope, and compare them with 21 higher luminosity quasar counterparts.2009ApJ...697..182Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/697/182CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/157 : The Extended 12um galaxy sample (Rush+ 1993)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/697/182https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/697/182http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/697/182https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/697/182https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/697/182http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/697/182GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/697/182/sample (Observations, galaxy data,)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/697/182/sample?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/697/182/sample?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/697/182/sample?GETtext/xml+votable180.050000true10.1925-79.240.0055555555555555566/941 2104 2245 2309 4439 4488 5244 5284 5481 5687 5731 6977 7552 7642 7713 7777 7921 8845 8881 8922 8941 10265 10472 10709 10912 10927 11206 11490 11924 12380 18794 19283 19416 19932 23233 23323 25054 25135 26148 26292 26509 27191 28356 28517 32931 33958 34294 43806 43877 45779 46615 490426.6214843819315255e-21 3.972891923313128e-20https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/697/182?format=asciiInfrareddefaultJ/ApJ/697/182/sampleObservations, galaxy data,recnoRecord number assigned by the VizieR team.
