The sample contains 203 extragalactic sources from the 15um ELAIS-SWIRE survey, all with measured spectroscopic redshift. Most of these sources have full multiwavelength coverage from the FUV (GALEX) to the FIR (Spitzer) and lie in the redshift range 0.1<z<1.3. This large sample allows us for the first time to characterize the spectral properties of sources responsible for the strong evolution observed in the MIR. Based on SED-fitting, we have classified the MIR sources, identifying AGN signatures in about 50% of them. This fraction is significantly higher than that derived from optical spectroscopy (~29%) and is due in particular to the identification of AGN activity in objects spectroscopically classified as galaxies (the spectroscopic classification may be somewhat unreliable because of host galaxy dilution in the optical). It is likely that in most of our objects, the AGN is either obscured or low luminosity, and thus dominates the energetic output only in the MIR, showing up just in the range where the host galaxy SED has a minimum. The fraction of AGNs strongly depends on flux density, with that derived through the SED-fitting about 20% at S_15um_~0.5-1mJy and gradually increasing to 100% at S_15um_>10mJy, while that obtained from optical spectroscopy is never >30%, even at higher flux densities.2008ApJ...684..136Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/684/136CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/MNRAS/325/1173 : ISO ELAIS 15{mu}m survey (Lari+, 2001)J/AJ/127/3075 : Mid-infrared population of ELAIS-S1 sample (La Franca+,J/MNRAS/351/1290 : ELAIS: final band-merged catalogue (Rowan-Robinson+, 2004)J/MNRAS/358/333 : ELAIS optical ident. at 15um + 1.4GHz (Gonzalez-Solares+,J/MNRAS/358/397 : Final analysis of ELAIS 15-{mu}m (Vaccari+, 2005)J/A+A/451/881 : ESIS BVR catalog, ELAIS-S1 (Berta+, 2006)J/A+A/476/151 : SWIRE ELAIS-S1 IR-peak galaxy IR fluxes (Berta+, 2007)J/ApJ/703/1778 : Spitzer sources in SWIRE/XMM/ELAIS-S1 field (Sacchi+, 2009)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/684/136https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/684/136http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/684/136https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/684/136https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/684/136http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/684/136GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/684/136/table1 (Multiwavelength properties of the 15um sources in the ELAIS-S1 field (from erratum in 2009ApJ...701..850G))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/684/136/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/684/136/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/684/136/table1?GETtext/xml+votable180.050000true7.2017917-43.116250.0055555555555555566/35387 35388 35390 35473 35474 35475 35476 354781.0763920601544068e-21 1.4134638842407062e-18https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/684/136?format=asciiUVOpticalInfrareddefaultJ/ApJ/684/136/table1Multiwavelength properties of the 15um sources in the ELAIS-S1 field (from erratum in 2009ApJ...701..850G)SpClOptical spectroscopy object type (6)src.classcharrecnoRecord number assigned by the VizieR team.
