cds-question@unistra.frmagellanic-cloudsmolecular-cloudsco-line-emissionradio-sourcesWe present a CO(2-1) survey at 9pc resolution obtained with the APEX telescope in the Small Magellanic Cloud (SMC). We perform a catalog of 177 molecular clouds in an extensive region (0.4kpc^2^) of the SMC. We use the CPROPS algorithm to identify the molecular clouds and estimate their main CO parameters. We analyze the scaling relations between the radius, velocity dispersion, luminosity, and virial mass of the SMC clouds, and they are compared with those of other low-metallicity galaxies. We also analyze the mass spectrum of the SMC by using the cumulative mass distribution. We study the dynamic state and stability of dust clouds associated with CO emission within our observed area. We estimate the viral mass- and dust-based CO-to-H2 conversion factor of the SMC. Finally, we study the link between molecular clouds and star-forming regions.2023A&A...672A.153Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/672/A153CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/672/A153https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/672/A153http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/672/A153https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/672/A153https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/672/A153http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/672/A153GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/672/A153/table2 (Parameters of CO(2-1) clouds in the SMC)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/672/A153/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/672/A153/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/672/A153/table2?GETtext/xml+votable180.050000true11.24-73.1686110.005555555555555556Cone search capability for table J/A+A/672/A153/list (List of fits datacubes)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/672/A153/list?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/672/A153/list?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/672/A153/list?GETtext/xml+votable180.050000true11.7325-73.2366390.0055555555555555566/33294-33295 33297 33299 33304 33306 33316-33317 33328https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/672/A153?format=asciiRadiodefaultJ/A+A/672/A153/table2Parameters of CO(2-1) clouds in the SMCN[1/177] Cloud numbermeta.id;meta.mainintrecnoRecord number assigned by the VizieR team.
