cds-question@unistra.frgalaxiesinfrared-sourcessurveysThe Spitzer Interacting Galaxies Survey is a sample of 103 nearby galaxies in 48 systems, selected using association likelihoods and therefore free from disturbed morphology biases. All galaxies have been observed with Infrared Array Camera and MIPS 24{mu}m bands from the Spitzer Space Telescope. This catalog presents the global flux densities and colors of all systems and correlations between the interacting systems and their specific star formation rate (sSFR). This sample contains a wide variety of galaxy interactions with systems ranging in mass, mass ratios, and gas-content as well as interaction strength. This study seeks to identify the process of triggering star formation in galaxy interactions, therefore, we focus on the non-active galactic nucleus spiral galaxies only. From this subset of 70 spiral galaxies we have determined that this sample has enhanced sSFR compared to a sample of non-interacting field galaxies. Through optical data we have classified each system by "interaction strength"; the strongly interacting (Stage 4) galaxies have higher sSFR values than the weakly (Stage 2) and moderately (Stage 3) interacting systems. However, the Stage 2 and 3 systems have statistically identical sSFR properties, despite the lack of optical interaction signatures exhibited by the Stage 2 galaxies. We suggest that the similarity of sSFR in these stages could be a consequence of some of these Stage 2 systems actually being post-perigalactic and having had sufficient time for their tidal features to fade to undetectable levels. This interpretation is consistent with the correlation of sSFR with separation, which we have determined to have little variation up to 100kpc.2015ApJS..218....6Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/218/6CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/221 : PSCz catalog (Saunders+, 2000)VII/155 : Third Reference Cat. of Bright Galaxies (RC3) (de Vaucouleurs+ 1991)VII/74 : Atlas of Peculiar Galaxies (Arp 1966)J/PASP/123/1011 : Star Formation Reference Survey (SFRS) (Ashby+, 2011)J/ApJ/714/1256 : Far-IR star formation rate indicators (Calzetti+, 2010)J/ApJ/713/330 : Spitzer observations of major-merger galaxies (Xu+, 2010)J/ApJ/703/1672 : Far-IR and H{alpha} fluxes in galaxies (Kennicutt+, 2009)J/ApJ/703/517 : The Spitzer Local Volume Legacy: IR photometry (Dale+, 2009)J/ApJ/692/556 : Star forming galaxy templates (Rieke+, 2009)J/ApJ/676/184 : Peculiar motion away from the Local Void (Tully+, 2008)J/AJ/133/791 : Spitzer phot. of normal & interacting galaxies (Smith+, 2007)J/ApJ/633/871 : Positions & photometry of HII knots in M51 (Calzetti+, 2005)J/AJ/128/2170 : H{alpha} imaging of irregular galaxies (Hunter+, 2004)J/ApJS/132/37 : Spectroscopy of Southern warm IR galaxies (Kewley+, 2001)J/ApJS/112/315 : Spectroscopic parameters of Seyfert nuclei (Ho+ 1997)http://edd.ifa.hawaii.edu/ : The Extragalactic Distance Database (EDD)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/218/6https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/218/6http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/218/6https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/218/6https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/218/6http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/218/6GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/218/6/sigs (Basic properties, Spitzer flux densities and derived physical properties for all SIGS galaxies)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/218/6/sigs?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/218/6/sigs?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/218/6/sigs?GETtext/xml+votable180.050000true12.7577917-7.05705280.0055555555555555566/556 614 4439 4447 4469 5082 5241 5244 5463 5634 5635 6037 6098 6539 7584 7602 7604 7606 7986 8173 8196 8492 9882 10515 10544 10628 10637 10739 10900 10901 11027 11372 11389 11434 17492 17927 18209 18212 18731 18809 23178 25344 25739 25888 25890 27255 27426 27741 27907 28045 28225 28593 367166.772611666688002e-21 6.185923063528282e-20https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/218/6?format=asciiInfrareddefaultJ/ApJS/218/6/table2Spitzer observations logrecnoRecord number assigned by the VizieR team.
