cds-question@unistra.frgalaxiesinfrared-sourceschemical-abundancesinfrared-photometryUsing infrared photometry from the Spitzer Space Telescope, we perform the first inventory of aromatic feature emission (also commonly referred to as polycyclic aromatic hydrocarbon emission) for a statistically complete sample of star-forming galaxies in the local volume. The photometric methodology involved is calibrated and demonstrated to recover the aromatic fraction of the Infrared Array Camera 8um flux with a standard deviation of 6% for a training set of 40 SINGS galaxies (ranging from stellar to dust dominated; Kennicutt et al. 2003PASP..115..928K) with both suitable mid-infrared Spitzer Infrared Spectrograph spectra and equivalent photometry. A potential factor of 2 improvement could be realized with suitable 5.5um and 10um photometry, such as what may be provided in the future by the James Webb Space Telescope. The resulting technique is then applied to mid-infrared photometry for the 258 galaxies from the Local Volume Legacy (LVL; Dale et al. 2009, Cat. J/ApJ/703/517) survey, a large sample dominated in number by low-luminosity dwarf galaxies for which obtaining comparable mid-infrared spectroscopy is not feasible. Using oxygen abundances compiled from the literature for 129 of the 258 LVL galaxies, we find a correlation between metallicity and the aromatic-to-total infrared emission ratio but not the aromatic-to-total 8um dust emission ratio. A possible explanation is that metallicity plays a role in the abundance of aromatic molecules relative to the total dust content, but other factors, such as star formation and/or the local radiation field, affect the excitation of those molecules.2010ApJ...715..506Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/715/506CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/233 : The 2MASS Extended sources (IPAC/UMass, 2003-2006)J/ApJS/190/233 : Spectroscopy and abundances of SINGS galaxies (Moustakas+,J/ApJ/703/517 : The Spitzer Local Volume Legacy (LVL) (Dale+, 2009)J/ApJ/701/1965 : Radial dust properties of SINGS galaxies (Munoz-Mateos+,J/ApJ/656/770 : Mid-IR spectrum of star-forming galaxies (Smith+, 2007)J/AJ/133/715 : Dwarf galaxies of the Local Group (Whiting+, 2007)J/ApJS/164/81 : Spectrophotometry of nearby galaxies (Moustakas+, 2006)J/A+A/448/955 : Abundances of emission galaxies in SDSS-DR3 (Izotov+, 2006)J/PASP/117/227 : Properties of 101 galaxies from the NFGS (Kewley+, 2005)J/ApJS/153/429 : SDSS strong emission line HII galaxies (Kniazev+, 2004)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/715/506https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/715/506http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/715/506https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/715/506https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/715/506http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/715/506GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/715/506/table1 (Local Volume Legacy (LVL) and SINGS galaxies)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/715/506/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/715/506/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/715/506/table1?GETtext/xml+votable180.050000true0.492083-15.4608330.0055555555555555566/396 764 2121 2130 2155 2282 4181 4447 4511 5061 5067 5116 5132 5142 5174 5181 5202 5203 5230 5283 5287 5329 5504 5584 5607 5636 5715 5799 5978 6042 6502 6604 6605 6623 6649 7239 7241 7471 7523 7530 7577 7582 7599 7600 7602 7603 7604 7606 7607 7618 7622 7624 7649 7650 7743 7769 7786 7799 7878 7946 7956 7970 8120 8908 10153 10265 10475 10532 10538 10561 10607 10627 10659 10755 10761 10762 10767 10793 10798 10799 10800 10809 10818 10840 10841 10847 10856 10881 10888 10896 10897 10900 10901 10905 10908 10910 10911 10935 10941 10954 10959 10970 10976 10977 10979 10986 10998 10999 11006 11019 11027 11030 11045 11084 11092 11120 11127 11140 11143 11227 11263 11434 11444 11448 11457 11639 11681 11696 11933 11944 11961 11965 12047 12199 13522 13637 15592 16441 16459 16519 16544 16595 16605 16655 16682 16695 16697 16701 16744 16779 16833 17165 17594 17612 18032 18041 18378 18398 18419 18429 19717 19779 19990 21026 21027 24912 24952 24956 25017 25083 25946 26047 26271 26814 26858 26977 27030 27055 27351 27375 27383 27465 27512 27514 27555 27568 27591 27604 27643 27830 27861 27926 28015 28035 28087 28091 28149 28167 28172 28173 28184 28451 28468 28496 28510 28535 28608 28610 28631 28636 28637 28666 33096 33151 33193 33265 33295 33571 33655 33656 33685 33832 33927 33958 33966 33986 34297 34401 34403 34404 34471 34493 34641 35206 35214 35243 35482 35514 35536 35993 36164 36194 38841 38846 43706 43874 43878 43881 43883 43925 43972 45305 45367 45777 45914 45937 46339 46399 46460 46545 46549 46597 489426.772611666688002e-21 4.923046907857898e-20https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/715/506?format=asciiInfrareddefaultJ/ApJ/715/506/table1Local Volume Legacy (LVL) and SINGS galaxiesSimbadNameSimbad column added by the CDSmeta.idcharNameGalaxy namemeta.id;meta.maincharprimaryrecnoRecord number assigned by the VizieR team.
