cds-question@unistra.frh-ii-regionsmolecular-cloudsinfrared-photometryWe present sub-arcsecond (0.35-0.9"), near-infrared J-, H- and K-band photometric observations of six fields along the W51 giant molecular cloud (W51 GMC). Our observations reveal four new, embedded clusters and provide a new high-resolution (0.35") view of the W51 IRS2 (G49.5-0.4) region. The cluster associated with G48.9-0.3 is found to be a double cluster enclosed in a nest of near-infrared nebulosity. We construct stellar surface density maps for four major clusters in the W51 GMC. These unveil the underlying hierarchical structure.2004MNRAS.353.1025Nhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/353/1025CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/353/1025https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/353/1025http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/353/1025https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/353/1025https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/353/1025http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/353/1025GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/353/1025/w51 (Combined table from original tables)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/353/1025/w51?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/353/1025/w51?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/353/1025/w51?GETtext/xml+votable180.050000true290.5684416714.047013890.0055555555555555566/30694https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/353/1025?format=asciiInfrareddefaultJ/MNRAS/353/1025/w51Combined table from original tablesrecnoRecord number assigned by the VizieR team.
