cds-question@unistra.frgalaxiesline-intensitiesgravitational-lensingWe measure [C III] 1907, C III] 1909{AA} emission lines in 11 gravitationally lensed star-forming galaxies at z~1.6-3, finding much lower equivalent widths than previously reported for fainter lensed galaxies. While it is not yet clear what causes some galaxies to be strong C III] emitters, C III] emission is not a universal property of distant star-forming galaxies. We also examine C III] emission in 46 star-forming galaxies in the local universe, using archival spectra from GHRS, FOS, and STIS on HST and IUE. Twenty percent of these local galaxies show strong C III] emission, with equivalent widths <-5{AA}. Three nearby galaxies show C III] emission equivalent widths as large as the most extreme emitters yet observed in the distant universe; all three are Wolf-Rayet galaxies. At all redshifts, strong C III] emission may pick out low-metallicity galaxies experiencing intense bursts of star formation. Such local C iii] emitters may shed light on the conditions of star formation in certain extreme high-redshift galaxies.2015ApJ...814L...6Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/814/L6CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/294 : The SDSS Photometric Catalog, Release 7 (Adelman-McCarthy+, 2009)J/A+A/529/A149 : HII regions in low-metallicity galaxies (Guseva+, 2011)J/ApJS/164/81 : Spectrophotometry of nearby galaxies (Moustakas+, 2006)J/A+AS/136/35 : WR galaxies and HII regions catalog (Schaerer+ 1999)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/814/L6https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/814/L6http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/814/L6https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/814/L6https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/814/L6http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/814/L6GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/814/L6/table1 (Galaxy samples, properties, and equivalent widths)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/814/L6/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/814/L6/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/814/L6/table1?GETtext/xml+votable180.050000true51.86375-13.43583330.0055555555555555566/3389 4876 5026 5419 6098 6347 7252 7281 7381 7437 7743 7763 7878 7926 8260 10011 10144 10689 10769 10841 11126 11132 11434 16884 17405 17771 17904 18307 19089 19910 20183 22828 22974 24696 25169 25731 25737 27045 27356 27657 27937 28086 28147 28631 36331 38849 40255 43429 43859 43874 44236 46399 47701https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/814/L6?format=asciidefaultJ/ApJ/814/L6/table1Galaxy samples, properties, and equivalent widthsSimbadNameSimbad column added by the CDSmeta.idcharnullableFilt[Rg] Filter for galaxy/object, AB magnitudemeta.id;instr.filtercharrecnoRecord number assigned by the VizieR team.
