cds-question@unistra.frastrophysical-masersradio-astronomyinterferometryWe present the results of a high angular resolution Very Large Array (VLA) Class I 44GHz and Class II 6.7GHz CH_3_OH maser survey of a sample of ~20 massive young stellar object (MYSO) outflow candidates selected on the basis of extended 4.5um emission in Spitzer Galactic Legacy Infrared Mid-Plane Survey Extraordinaire images. These 4.5um selected candidates are referred to as extended green objects (EGOs), for the common coding of this band as green in three-color Infrared Array Camera images. The detection rate of 6.7GHz Class II CH_3_OH masers, which are associated exclusively with massive YSOs, toward EGOs is >~64% - nearly double the detection rate of surveys using other MYSO selection criteria. The detection rate of Class I 44GHz CH_3_OH masers, which trace molecular outflows, is ~89% toward EGOs associated with 6.7GHz CH_3_OH masers.2009ApJ...702.1615Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/702/1615CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/136/2391 : GLIMPSE Extended Green Objects catalog (Cyganowski+, 2008)J/ApJS/155/149 : CH_3_OH 7_0_-6_1_ A^+^ maser sources (Kurtz+, 2004)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/702/1615https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/702/1615http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/702/1615https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/702/1615https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/702/1615http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/702/1615GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/702/1615/sample (Extended Green Objects (EGO) sample (table 5 and positions from table 4))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/702/1615/sample?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/702/1615/sample?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/702/1615/sample?GETtext/xml+votable180.050000true272.205417-20.099250.005555555555555556Cone search capability for table J/ApJ/702/1615/masers (Fitted properties of masers at 6.7GHz (table7) and 44GHz (table8))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/702/1615/masers?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/702/1615/masers?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/702/1615/masers?GETtext/xml+votable180.050000true272.2056625-20.099719170.0055555555555555566/29091 29094 29507 29508 29510 29529 29532 29535 30218 30219 30256 30405 30420 30423 306948.27688880188539e-21 8.27688880188539e-21https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/702/1615?format=asciiRadiodefaultJ/ApJ/702/1615/sampleExtended Green Objects (EGO) sample (table 5 and positions from table 4)recnoRecord number assigned by the VizieR team.
