cds-question@unistra.fractive-galactic-nucleix-ray-sourcesinfrared-sourcesMeasuring the star-forming properties of active galactic nucleus (AGN) hosts is key to our understanding of galaxy formation and evolution. However, this topic remains debated, partly due to the difficulties in separating the infrared (i.e. 1-1000um) emission into AGN and star-forming components. Taking advantage of archival far-infrared data from Herschel, we present a new set of AGN and galaxy infrared templates and introduce the spectral energy distribution fitting code IRAGNSEP. Both can be used to measure infrared host galaxy properties, free of AGN contamination. To build these, we used a sample of 100 local (z<0.3), low-to-high luminosity AGNs (i.e. L_bol_~10^42-46^erg/s), selected from the 105-month Swift-BAT X-ray survey, which have archival Spitzer-IRS spectra and Herschel photometry. We first built a set of seven galaxy templates using a sample of 55 star-forming galaxies selected via infrared diagnostics. Using these templates, combined with a flexible model for the AGN contribution, we extracted the intrinsic infrared emission of our AGN sample. We further demonstrate that we can reduce the diversity in the intrinsic shapes of AGN spectral energy distributions down to a set of three AGN templates, of which two represent AGN continuum, and one represents silicate emission. Our results indicate that, on average, the contribution of AGNs to the far-infrared ({lambda}>=50um) is not as high as suggested by some recent work. We further show that the need for two infrared AGN continuum templates could be related to nuclear obscuration, where one of our templates appears dominated by the emission of the extended polar dust.2021MNRAS.503.2598Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/503/2598CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/503/2598https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/503/2598http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/503/2598https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/503/2598https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/503/2598http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/503/2598GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/503/2598/tablec12 (Main properties of the 112 sources in our AGN sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/503/2598/tablec12?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/503/2598/tablec12?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/503/2598/tablec12?GETtext/xml+votable180.050000true135.153620.89460.005555555555555556Cone search capability for table J/MNRAS/503/2598/tablec45 (Basic properties of this 110 galaxies)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/503/2598/tablec45?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/503/2598/tablec45?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/503/2598/tablec45?GETtext/xml+votable180.050000true354.058716672.155143890.0055555555555555565/2287 6/226 627 687 700 953 1008 1677 2363 2518 3506 4215 4439 4447 4540 4834 4867 4990 5712 5931 6047 6068-6069 6077-6078 6212 6499 6752 7132 7157 7184 7246 7309 7386 7424 7552 7659 7728 7869 8017 8071 8085 8216 8299 8482 8845 8922 9052 9144 9147 9262 9469 9471 9634 9640-9641 9824 9894 10144 10147 10150 10156 10158 10189-10190 10200 10210 10440 10454 10513 10516-10518 10716 10752 10912 10977 11006 11071 11101 11388 11416 11520 13021 13120 13184 15323 16690 16758 16784 17252 17492 17525 17683 17688 17692 17727 17814 17904 18034 18484 18524 18794 18809 18897 19283 19296 19373 19932 20000 20061 20118 20254 20379 20556 21016 21237 21450 21847 21996 22626 22890 22975 23059 23198 23921 24123 24144 24842 24855 25182 25403 25610 25735 25742 25790 25907 26300 26317 26393 26811 27258-27259 27321 27699 27724 27734 27767 28188 28350 28356 28471 28593 28609 28999 31158 31503 32740 34273 34881 35246 35284 35330 35623 35993 36158 36216 36756 36786 36831 36896 38285 38653 38696 38868 40124 40221 40410 40818 41276 41982 42016 43634 43677 43806 43877 44551 44660 44785 45883 46077 46101 46399 46544 46811 46987 47029 47120 47154 48665 490423.972892068905477e-22 2.837779945223663e-21https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/503/2598?format=asciiX-rayInfrareddefaultJ/MNRAS/503/2598/tablec12Main properties of the 112 sources in our AGN sampleSimbadNameSimbad column added by the CDSmeta.idcharnullablerecnoRecord number assigned by the VizieR team.
