cds-question@unistra.fractive-galactic-nucleigamma-ray-astronomyseyfert-galaxiesquasarsastronomical-object-identificationsurveysWe present the analysis of 2.1 years of Fermi Large Area Telescope (LAT) data on 491 Seyfert galaxies detected by the Swift Burst Alert Telescope (BAT) survey. Only the two nearest objects, NGC 1068 and NGC 4945, which were identified in the Fermi first year catalog (Abdo et al. 2010, Cat. J/ApJ/715/429), are detected. Using Swift/BAT and radio 20cm fluxes, we define a new radio-loudness parameter R_X,BAT_ where radio-loud objects have logR_X,BAT_> -4.7. Based on this parameter, only radio-loud sources are detected by Fermi/LAT. An upper limit to the flux of the undetected sources is derived to be ~2x10^-11^photons/cm^2^/s, approximately seven times lower than the observed flux of NGC 1068. Assuming a median redshift of 0.031, this implies an upper limit to the {gamma}-ray (1-100GeV) luminosity of <~3x10^41^erg/s. In addition, we identified 120 new Fermi/LAT sources near the Swift/BAT Seyfert galaxies with significant Fermi/LAT detections. A majority of these objects do not have Swift/BAT counterparts, but their possible optical counterparts include blazars, flat-spectrum radio quasars, and quasars.2011ApJ...742...66Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/742/66CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/726/16 : {gamma}-ray loud blazars (Linford+, 2011)J/ApJ/715/429 : First Fermi-LAT AGN catalog (1LAC) (Abdo+, 2010)J/ApJS/188/405 : Fermi-LAT first source catalog (1FGL) (Abdo+, 2010)J/ApJ/699/603 : Evolution of Swift/BAT blazars (Ajello+, 2009)J/A+A/495/691 : Multifrequency cat. of blazars, Roma-BZCAT (Massaro+, 2009)J/ApJS/175/97 : CGRaBS: {gamma}-ray blazar candidates (Healey+, 2008)http://fermi.gsfc.nasa.gov/ : Fermi Gamma-ray telescope home pagehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/742/66https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/742/66http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/742/66https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/742/66https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/742/66http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/742/66GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/742/66/table2 (Fermi/LAT sources without Swift/BAT counterpart)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/742/66/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/742/66/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/742/66/table2?GETtext/xml+votable180.050000true11.3971-37.28960.0055555555555555566/110 573 860 968 1285 1305 2331 3712 5154 5404 5596 5693 5771 5848 6062 6110 6498 6532 6588 6636 6923 6978 7623 7936 7951 8004 8054 8091 8177 8717 8818 9618 9634 9641 9821 9906 10006 10427 10627 10949 11457 11640 12251 16736 17602 17843 19718 23263 23417 25444 26097 26276 26553 27061 27223 27857 28068 28086 28138 31111 31566 33214 33238 33570 33818 33881 33970 34038 34492 35533 35790 35832 36155 36328 36332 36344 36602 37884 38369 38759 38797 38803 40191 40194 40344 40353 40392 40412 40633 42131 43782 43888 43985 43993 44011 44170 44777 44971https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/742/66?format=asciiGamma-raydefaultJ/ApJ/742/66/table2Fermi/LAT sources without Swift/BAT counterpartSimbadNameSimbad column added by the CDSmeta.ref.urlcharrecnoRecord number assigned by the VizieR team.
