cds-question@unistra.frseyfert-galaxiesinfrared-photometrymillimeter-astronomyphotometrysubmillimeter-astronomyWe present far-infrared (FIR) 70-500{mu}m imaging observations obtained with Herschel/Photodetector Array Camera (PACS) and Spectral and Photometric Imaging REceiver (SPIRE) of 33 nearby (median distance of 30Mpc) Seyfert galaxies from the Revised Shapley-Ames (RSA) catalogue. We obtain the FIR nuclear (r=1kpc and r=2kpc) and integrated spectral energy distributions (SEDs). We estimate the unresolved nuclear emission at 70{mu}m and we fit the nuclear and integrated FIR SEDs with a grey body model. We find that the integrated FIR emission of the RSA Seyferts in our sample is dominated by emission from the host galaxy, with dust properties similar to those of normal galaxies (non-AGN). We use four criteria to select galaxies whose nuclear 70{mu}m emission has a significant AGN contribution: (1) elevated 70/160{mu}m flux ratios, (2) spatially resolved, high dust temperature gradient, (3) 70{mu}m excess emission with respect to the fit of the FIR SEDs with a grey body, and (4) excess of nuclear SFR obtained from 70{mu}m over SFR from mid-infrared indicators. 16 galaxies (48 per cent of the initial sample) satisfy at least one of these conditions, whereas 10 satisfy half or more. After careful examination of these, we select six bona fide candidates (18 per cent of the initial sample) and estimate that ~40-70 per cent of their nuclear (r=1-2kpc) 70{mu}m emission is contributed by dust heated by the AGN.2016MNRAS.458.4512Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/458/4512CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/458/4512https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/458/4512http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/458/4512https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/458/4512https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/458/4512http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/458/4512GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/458/4512/table1 (Galaxy sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/458/4512/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/458/4512/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/458/4512/table1?GETtext/xml+votable180.050000true196.6088392-40.41460940.0055555555555555566/1008 4439 7132 10364 10912 10927 10977 17754 20000 20014 21450 23171 25083 25907 27767 27914 28123 28517 34273 34531 34534 38268 38704 40221 40410 43634 43677 43925 45883 46399 46615 46811 469873.972892068905477e-22 5.101838343667421e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/458/4512?format=asciiInfraredMillimeterdefaultJ/MNRAS/458/4512/table7Integrated photometryrecnoRecord number assigned by the VizieR team.
