cds-question@unistra.frmilky-way-galaxyopen-star-clustersstellar-associationsgalaxy-classification-systemsWe carried out a search for new infrared star clusters, stellar groups and candidates using WISE images, which are very sensitive to dust emission nebulae. We report the discovery of 437 embedded clusters and stellar groups that show a variety of structures, both in the stellar and nebular components. Pairs or small groupings of clusters are observed, suggesting multiple generations at the early formation stages. The resulting catalogue provides Galactic and equatorial coordinates, together with angular sizes for all objects. The nature of a representative test sub-sample of 14 clusters is investigated in detail by means of 2MASS photometry. The colour magnitude diagrams and radial density distributions characterise them as stellar clusters. The 437 new objects were found in the ranges 145{deg}<.l<=290{deg} and -25{deg}<=b<=20{deg}, and they appear to be a major object source for future studies of star cluster formation and their early evolution. WISE is a powerful tool to further probe for very young clusters throughout the disk.2015NewA...34...84Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/other/NewA/34.84CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/311 : WISE All-Sky Data Release (Cutri+ 2012)V/112 : Catalog of Star-Forming Regions in the Galaxy (Avedisova 2002)J/A+A/447/921 : Galactic Open Cluster Candidates (Kronberger+, 2006)J/A+A/532/A131 : New Galactic star clusters in VVV survey (Borissova+, 2011)J/A+A/542/A3 : Stellar clusters from UKIDSS GPS (Solin+, 2012)J/A+A/562/A54 : Galactic open clusters in RAVE (Conrad+, 2014)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/other/NewA/34.84https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/other/NewA/34.84http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/other/NewA/34.84https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/other/NewA/34.84https://vizier.iucaa.in/viz-bin/votable?-source=J/other/NewA/34.84http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/other/NewA/34.84GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/other/NewA/34.84/table1 (The new list of star clusters or candidates)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/other/NewA/34.84/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/other/NewA/34.84/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/other/NewA/34.84/table1?GETtext/xml+votable180.050000true71.1333361.200830.0055555555555555565/5416 5511 5995 9342 9427 9430 9463 9816 6/927 1285 1287 1293 1298 1299 1301 1303 1305 1308 1319 1328 1344 1436 1538 1544 2006 2012 3349 3351 4778 4779 4780 4782 4783 6148 21301 21315 21336 21395 21396 21404 21425 21638 21640 21642 21643 21646 21647 21658 21668 21670 21680 21681 21683 21689 21690 21691 21693 22036 22038 22039 22082 22088 22090 22115 22122 22123 22208 22416 22500 22509 23670 23671 23762 23763 23772 23773 23936 23938 23969 23977 23992 23996 23999 24256 24325 24507 24510 37242 37363 37366 37372 37374 37713 37715 37716 37718 37719 37725 37732 37733 37744 37745 37747 37754 37829 37842 37843 37844 37846 37847 37848 37851 37875 37876 37878 37881 37883 37884 38402 38538 39199 39221 39223 39242 39243 39248 39250 39258 39259 39268 39270 39271 39272 39273 39274 39276 39277 39278 39280https://cdsarc.cds.unistra.fr/viz-bin/moc/J/other/NewA/34.84?format=asciiOpticaldefaultJ/other/NewA/34.84/table1The new list of star clusters or candidatesCamargo[1/437] Target sequential numbermeta.recordintprimaryGLONGalactic longitudedegpos.galactic.lonGLATGalactic latitudedegpos.galactic.latfloatRAJ2000Right ascension (J2000)pos.eq.ra;meta.mainDEJ2000Declination (J2000)pos.eq.dec;meta.mainSize1Cluster size (major)arcminphys.angSizefloatSize2Cluster size (minor)arcminphys.angSizefloatTypeCluster type (1)src.classcharAved[y/n] Cross-identifications with Avedisova (2002ARep...46..193A, Cat.
