They show mixed stellar populations and the spectra of many NSCs indicate recent events of star formation. However, it is impossible to resolve external NSCs in order to examine the relevant processes. The Milky Way NSC, on the other hand, is close enough to be resolved into its individual stars and presents therefore a unique template for NSCs in general. Young, massive stars have been found by systematic spectroscopic studies at projected distances R&lt;~0.5pc from the supermassive black hole, Sagittarius A* (Sgr A*). In recent years, increasing evidence has been found for the presence of young, massive stars also at R&gt;0.5pc. Our goal in this work is a systematic search for young, massive star candidates throughout the entire region within R~2.5pc of the black hole.</description><source format="bibcode">2013A&amp;A...549A..57N</source><referenceURL>https://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/549/A57</referenceURL><type>Catalog</type><contentLevel>Research</contentLevel><relationship><relationshipType>IsServedBy</relationshipType><relatedResource ivo-id="ivo://CDS.VizieR/TAP">TAP VizieR generic service</relatedResource></relationship><relationship><relationshipType>IsServedBy</relationshipType><relatedResource>Conesearch service</relatedResource></relationship><relationship><relationshipType>related-to</relationshipType><relatedResource ivo-id="ivo://CDS.VizieR/J/ApJ/597/323">J/ApJ/597/323 : Cool stars at the Galactic Center (Blum+, 2003)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/ApJ/643/1011">J/ApJ/643/1011 : Early-type stars in the center of the Galaxy (Paumard+, 2006)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/A+A/499/483">J/A+A/499/483 : Galactci center sources NIR observations (Buchholz+, 2009)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/ApJ/697/1741">J/ApJ/697/1741 : Warped disks of YSOs in Galactic center (Bartko+, 2009)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/MNRAS/417/114">J/MNRAS/417/114 : HST/NICMOS Galactic Center survey catalogue (Dong+, 2011)</relatedResource></relationship></content><rights>https://cds.unistra.fr/vizier-org/licences_vizier.html</rights><capability><interface xsi:type="vr:WebBrowser"><accessURL use="full">https://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/549/A57</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/549/A57</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/549/A57</mirrorURL></interface></capability><capability><interface xsi:type="vs:ParamHTTP"><accessURL use="base">https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/549/A57</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/549/A57</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/549/A57</mirrorURL><queryType>GET</queryType><resultType>text/xml+votable</resultType></interface></capability><capability standardID="ivo://ivoa.net/std/TAP#aux"><interface xsi:type="vs:ParamHTTP" role="std"><accessURL use="base">https://tapvizier.cds.unistra.fr/TAPVizieR/tap</accessURL></interface></capability><capability xsi:type="cs:ConeSearch" standardID="ivo://ivoa.net/std/ConeSearch"><description>Cone search capability for table J/A+A/549/A57/table2 (Early-type star candidates in the Galactic Center)</description><interface xsi:type="vs:ParamHTTP" role="std"><accessURL use="base">https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/549/A57/table2?</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/549/A57/table2?</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/549/A57/table2?</mirrorURL><queryType>GET</queryType><resultType>text/xml+votable</resultType></interface><maxSR>180.0</maxSR><maxRecords>50000</maxRecords><verbosity>true</verbosity><testQuery><ra>266.4168625</ra><dec>-29.00748056</dec><sr>0.005555555555555556</sr></testQuery></capability><capability><description>Associated data</description><interface xsi:type="vr:WebBrowser"><accessURL use="full">https://cdsarc.cds.unistra.fr/assocdata/?obs_collection=J/A+A/549/A57</accessURL></interface></capability><coverage><spatial>6/28830</spatial><footprint ivo-id="ivo://ivoa.net/std/moc">https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/549/A57?format=ascii</footprint><waveband>Optical</waveband></coverage><tableset><schema><name>default</name><table><name>J/A+A/549/A57/table2</name><description>Early-type star candidates in the Galactic Center</description><column><name>Ctp</name><description>Counterparts (4)</description><ucd>meta.id</ucd><dataType xsi:type="vs:VOTableType" arraysize="16*">char</dataType></column><column><name>recno</name><description>Record number assigned by the VizieR team.
