The best place to study hard ionizing radiation in the local universe is in very metal- deficient blue compact dwarf (BCD) galaxies. We have carried out a MMT spectroscopic search for [NeV] {lambda}3426 (ionization potential of 7.1Ryd), [FeV] {lambda}4227 (ionization potential of 4Ryd), and HeII {lambda}4686 (ionization potential of 4Ryd) emission in a sample of 18 BCDs. We have added data from previous work and from the Data Release 3 of the Sloan Digital Sky Survey (Cat. <II/259>). In total, we have assembled a BCD high-ionization sample with [NeV] emission in four galaxies, [FeV] emission in 15 galaxies, and HeII emission in 465 galaxies.2005ApJS..161..240Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/161/240CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/259 : The SDSS Photometric Catalog, Release 3 (Abazajian+ 2005)J/ApJ/511/639 : Abundances in blue compact galaxies (Izotov+, 1999)J/AZh/79/867 : Abundances of HII regions in blue galaxies (Holovatyy+, 2002)J/ApJ/602/200 : HII regions abundances in blue compact galaxies (Izotov+ 2004)J/A+A/419/469 : Abundances in the galaxy HS 0837+4717 (Pustilnik+, 2004)J/ApJS/161/240 : High-ionization emission in metal-deficient BCDs (Thuan+,J/A+A/448/955 : Abundances of emission galaxies in SDSS-DR3 (Izotov+, 2006)J/ApJ/708/1076 : The WHIQII survey: compact blue galaxies (Tollerud+, 2010)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/161/240https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/161/240http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/161/240https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/161/240https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/161/240http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/161/240GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/161/240/table1 (General parameters of galaxies)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/161/240/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/161/240/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/161/240/table1?GETtext/xml+votable180.050000true54.41-5.0436110.0055555555555555566/5366 5607 6005 6046 6075 6419 7185 7208 7251 7281 7303 7381 7878 10769 10970 11434 19417 22890 23078 23566 25851 26142 27199 36785https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/161/240?format=asciiOpticaldefaultJ/ApJS/161/240/table1General parameters of galaxiesSimbadNameSimbad column added by the CDSmeta.idcharONameOther namemeta.idcharrecnoRecord number assigned by the VizieR team.
