cds-question@unistra.frgalaxiesinfrared-sourcesactive-galactic-nucleiinfrared-astronomyspectroscopyWe present an analysis of the extended mid-infrared (MIR) emission of the Great Observatories All-Sky LIRG Survey sample based on 5-15um low-resolution spectra obtained with the Infrared Spectrograph on Spitzer. We calculate the fraction of extended emission (FEE) as a function of wavelength for the galaxies in the sample, FEE_{lambda}_, defined as the fraction of the emission which originates outside of the unresolved component of a source at a given distance. We find that the FEE_{lambda}_ varies from one galaxy to another, but we can identify three general types of FEE_{lambda}_: one where FEE_{lambda}_ is constant, one where features due to emission lines and polycyclic aromatic hydrocarbons appear more extended than the continuum, and a third which is characteristic of sources with deep silicate absorption at 9.7um. The mean size of the LIRG cores at 13.2um is 2.6kpc. However, once the IR luminosity of the systems reaches the threshold of L_IR_~10^11.8^L_{sun}_, slightly below the regime of Ultra-luminous Infrared Galaxies (ULIRGs), all sources become clearly more compact, with FEE_13.2um_<~0.2, and their cores are unresolved. Our estimated upper limit for the core size of ULIRGs is less than 1.5kpc.2010ApJ...723..993Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/723/993CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/715/572 : GOALS UV and FIR properties (Howell+, 2010)J/MNRAS/405/2505 : Nuclear activity in ULIRGs (Nardini+, 2010)J/ApJ/709/884 : Role of starburst-AGN composites in LIRG mergers (Yuan+,J/MNRAS/395/1695 : Spitzer mid-IR spectroscopy of LIRGs (Hernan-Caballero+,J/ApJS/182/628 : Spitzer quasar and ULIRG evolution study (Veilleux+, 2009)J/ApJ/674/172 : Oxygen abundances of LIRGs and ULIRGs (Rupke+, 2008)J/MNRAS/375/115 : ULIRGs galaxies in SDSS, 2dF and 6dF (Hwang+, 2007)J/ApJ/658/778 : Spitzer mid-IR spectroscopy of z~2 ULIRGs (Yan+, 2007)J/A+A/467/565 : z=1-3 ULIRGs from the Spitzer SWIRE survey (Berta+, 2007)J/AJ/121/97 : K-band spectroscopy of ULIRGs (Murphy+, 2001)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/723/993https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/723/993http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/723/993https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/723/993https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/723/993http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/723/993GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/723/993/table1 (Properties of the sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/723/993/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/723/993/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/723/993/table1?GETtext/xml+votable180.050000true2.472525.9241670.0055555555555555566/226 231 286 295 538 627 629 650 700 1276 1521 1677 1701 1702 1865 1918 2309 2363 2433 2518 2680 3364 3446 3824 3934 4993 5116 5130 5523 5816 5865 6348 6781 7552 8106 8111 8482 8673 8997 9133 9770 9895 10081 10144 10210 10281 10404 10453 10465 10628 10716 11029 11101 11180 11206 11908 12537 13021 13184 13523 13632 14164 15323 15333 15570 16091 16690 16758 17075 17252 17492 17506 17904 18406 18432 18753 18932 19283 20060 20061 20118 20208 20254 20371 20895 20896 21016 21416 21747 22468 22721 22792 23339 23921 24123 24144 24163 24232 24293 24631 24855 24958 25462 25610 26028 26035 26198 26298 26324 26811 26932 27340 27537 28188 28393 28999 29439 29680 29937 30027 30383 30580 30810 30822 30879 31081 31158 31430 31503 32187 32548 32740 34010 34397 34531 34627 34695 35067 35576 35602 35608 37113 37564 37821 38129 38139 38246 38285 38786 38935 39472 39960 40082 40801 41276 41402 41430 42010 42855 43078 43082 43107 43147 43298 43389 43564 43925 43994 44626 44671 45387 46077 46079 46130 46794 46811 47029 47162 47543 47854 48665https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/723/993?format=asciiInfrareddefaultJ/ApJ/723/993/table1Properties of the sampleSimbadNameSimbad column added by the CDSmeta.idcharrecnoRecord number assigned by the VizieR team.
