cds-question@unistra.fractive-galactic-nucleiquasarsinfrared-sourcesredshiftedspectral-energy-distributionastronomical-modelsThe range of currently proposed active galactic nucleus (AGN) far-infrared templates results in uncertainties in retrieving host galaxy information from infrared observations and also undermines constraints on the outer part of the AGN torus. We discuss how to test and reconcile these templates. Physically, the fraction of the intrinsic AGN IR-processed luminosity compared with that from the central engine should be consistent with the dust-covering factor. In addition, besides reproducing the composite spectral energy distributions (SEDs) of quasars, a correct AGN IR template combined with an accurate library of star-forming galaxy templates should be able to reproduce the IR properties of the host galaxies, such as the luminosity-dependent SED shapes and aromatic feature strengths. We develop tests based on these expected behaviors and find that the shape of the AGN intrinsic far-IR emission drops off rapidly starting at ~20{mu}m and can be matched by an Elvis+ (1994, J/ApJS/95/1)-like template with a minor modification. Despite the variations in the near- to mid-IR bands, AGNs in quasars and Seyfert galaxies have remarkably similar intrinsic far-IR SEDs at {lambda}~20-100{mu}m, suggesting a similar emission character of the outermost region of the circumnuclear torus. The variations of the intrinsic AGN IR SEDs among the type-1 quasar population can be explained by the changing relative strengths of four major dust components with similar characteristic temperatures, and there is evidence for compact AGN-heated dusty structures at sub-kiloparsec scales in the far-IR.2017ApJ...841...76Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/841/76CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJS/95/1 : Atlas of Quasar Energy Distributions (Elvis+ 1994)J/ApJS/166/470 : SDSS-Spitzer type I QSOs IR photometry (Richards+, 2006)J/ApJ/653/127 : 9.7um silicate features in AGNs (Shi+, 2006)J/ApJ/666/806 : SED of Spitzer quasars (QUEST) (Netzer+, 2007)J/ApJ/663/81 : SED of hard X-ray selected AGN in XMDS (Polletta+, 2007)J/ApJ/656/770 : Mid-IR spectrum of star-forming galaxies (Smith+, 2007)J/AJ/136/2373 : Type 2 quasars from SDSS (Reyes+, 2008)J/ApJ/705/14 : Seyfert galaxies in the mid-IR (Deo+, 2009)J/ApJ/692/556 : Star forming galaxy templates (Rieke+, 2009)J/ApJ/714/1256 : Far-IR star formation rate indicators (Calzetti+, 2010)J/MNRAS/414/500 : Spitzer/IRS ATLAS project source (Hernan-Caballero+, 2011)J/ApJ/759/139 : Herschel+MIPS photom. of GOODS sources (Kirkpatrick+, 2012)J/ApJ/768/13 : FIR properties of SDSS type 1 quasars (Hanish+, 2013)J/ApJS/206/1 : Mid-IR properties of GOALS nearby LIRGs (Stierwalt+, 2013)J/MNRAS/439/1648 : Subarcsecond mid-infrared atlas of local AGN (Asmus+, 2014)J/A+A/565/A128 : Dust SED in HRS nearby galaxies (Ciesla+, 2014)J/ApJ/788/159 : 17 Seyfert 1 galaxies light curves (Koshida+, 2014)J/ApJS/214/23 : IR spectra and photometry of z<0.5 quasars (Shi+, 2014)J/ApJS/219/18 : LIRAS: LoCuSS IR AGN survey (Xu+, 2015)J/ApJ/824/70 : UV-FIR SED results of SDSS QSOs & their hosts (Dong+, 2016)J/MNRAS/458/4512 : Nearby Seyferts FIR emissions (Garcia-Gonzalez+, 2016)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/841/76https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/841/76http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/841/76https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/841/76https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/841/76http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/841/76GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/841/76/table2 (Host galaxy IR properties of the 24 Palomar-Green quasars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/841/76/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/841/76/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/841/76/table2?GETtext/xml+votable180.050000true11.44678814.17315640.005555555555555556Cone search capability for table J/ApJ/841/76/table5 (Properties of 101 SFGs in the GOALS sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/841/76/table5?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/841/76/table5?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/841/76/table5?GETtext/xml+votable180.050000true293.0928958-4.00029170.0055555555555555566/226 286 295 538 627 629 1276 1521 1677 1865 2363 2433 2518 2680 3364 3824 4215 5523 5865 6028 6348 6781 7998 8111 8482 8636 8893 8906 8941 9133 9262 9959 10039 10081 10144 10217 10269 10281 10453 10628 10694 11829 12537 12632 13184 13523 14164 15333 15570 16690 17252 17904 18127 18753 18932 19730 20118 20254 20371 20895 20896 21416 22468 22792 23339 24163 24232 24293 24631 24957 24958 25403 25462 26035 26198 26310 26324 26811 26859 26932 27023 27227 27293 27340 27537 28164 28999 29439 29680 29937 30383 30580 30810 30822 31503 32187 32548 32740 34010 34397 34627 35067 35608 37564 37821 38129 38246 38285 39472 40082 41402 42010 42855 43078 43082 43147 43298 43994 45387 46077 46794 47029 47162 47543 48665https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/841/76?format=asciiInfrareddefaultJ/ApJ/841/76/table2Host galaxy IR properties of the 24 Palomar-Green quasarsID[4/81] Object ID (1)meta.idintrecnoRecord number assigned by the VizieR team.
