cds-question@unistra.fractive-galactic-nucleiline-intensitiesinfrared-photometryredshiftedinfrared-astronomyspectroscopyExtragalactic sources from the IRAS Faint Source Catalog (FSC) that have the optically faintest magnitudes (E>~18) were selected by spatial coincidence with a source in the FIRST radio survey, and 28 of these sources have been observed with the Infrared Spectrograph on Spitzer (IRS). While an infrared source is always detected with the IRS at the FIRST position, only ~50% of the infrared sources are real FSC detections, as estimated from the number of sources for which the f_v_(25um) determined with the IRS is fainter than the sensitivity limit for the FSC. Sources have 0.12<z<1.0 and luminosities 43.3<log[{nu}L_{nu}_(5.5um)]<46.7erg/s, encompassing the range from local ULIRGs to the most luminous sources discovered by Spitzer at z~2. Detectable PAH features are found in 15 of the sources (54%), and measurable silicate absorption is found in 19 sources (68%); both PAH emission and silicate absorption are present in 11 sources. PAH luminosities are used to determine the starburst fraction of bolometric luminosity, and model predictions for a dusty torus are used to determine the AGN fraction of luminosity in all sources based on vL_v_(5.5um). Approximately half of the sources have luminosity dominated by an AGN and approximately half by a starburst.2008ApJ...683..114Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/683/114CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/156 : IRAS Faint Source Catalog, |b| > 10, Version 2.0 (Moshir+ 1989)VIII/71 : The FIRST Survey Catalog, Version 03Apr11 (Becker+ 2003)J/ApJ/642/673 : IR-selected obscured AGN candidates (Polletta+, 2006)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/683/114https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/683/114http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/683/114https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/683/114https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/683/114http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/683/114GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/683/114/sources (IRS properties and luminosities of faint IRAS sources)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/683/114/sources?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/683/114/sources?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/683/114/sources?GETtext/xml+votable180.050000true112.300416761.31486110.0055555555555555566/4412 4886 5176 5795 5957 7269 7724 8419 8520 8973 9077 9205 9210 9225 9502 9752 9879 9936 10422 11030 11274 11492 25936 27362 31327 31339 31350 314429.276497240453405e-25 1.7003137259100215e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/683/114?format=asciiOpticalInfrareddefaultJ/ApJ/683/114/sourcesIRS properties and luminosities of faint IRAS sourcesrecnoRecord number assigned by the VizieR team.
