J/AJ/133/791 Spitzer photometry of normal & interacting galaxies (Smith+, 2007)

The Spitzer spirals, bridges, and tails interacting galaxy survey: interaction-induced star formation in the mid-infrared. Smith B.J., Struck C., Hancock M., Appleton P.N., Charmandaris V., Reach W.T. <Astron. J., 133, 791-817 (2007)> =2007AJ....133..791S
ADC_Keywords: Galaxies, IR ; Galaxies, photometry ; Photometry, infrared Keywords: galaxies: interactions - galaxies: starburst - infrared: galaxies Abstract: We present Spitzer mid-infrared imaging of a sample of 35 tidally distorted premerger interacting galaxy pairs selected from the Arp Atlas. We compare their global mid-infrared properties with those of normal galaxies from the SINGS Spitzer Legacy survey, and separate the disk emission from that of the tidal features. The [8.0um]-[24um], [3.6um]-[24um], and [5.8um]-[8.0um] colors of these optically selected interacting galaxies are redder on average than those of spirals, implying enhancements to the mass-normalized star formation rates (SFRs) of a factor of ∼2.

Note (1): Includes the IRAS flux from both galaxies in the pair. Note (2): Flags as follows: b = Nuclear spectral type from Dahari (1985ApJS...57..643D). c = Nuclear spectral type from Keel et al. (1985AJ.....90..708K). d = The bright galaxy in the Arp (1966, Cat. VII/74) Atlas photograph of Arp 136 is NGC 5820. This galaxy has a nearby similar-mass companion, NGC 5821, at the same redshift, outside of the Arp Atlas field of view. The second small galaxy in the Arp Atlas image is a background galaxy.
