cds-question@unistra.frmolecular-cloudsinterstellar-mediuminfrared-sourcesmillimeter-astronomysubmillimeter-astronomyInfrared dark clouds (IRDCs) are dense molecular clouds seen as extinction features against the bright mid-infrared Galactic background. Millimeter continuum maps toward 38 IRDCs reveal extended cold dust emission to be associated with each of the IRDCs. IRDCs range in morphology from filamentary to compact and have masses of 120 to 16000M_{sun}_, with a median mass of 940M_{sun}_. Each IRDC contains at least one compact (0.5pc) dust core and most show multiple cores. We find 140 cold millimeter cores unassociated with MSX 8{mu}m emission.2006ApJ...641..389Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/641/389CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toV/114 : MSX6C Infrared Point Source Catalog (Egan+ 2003)J/ApJ/639/227 : MSX IRDC candidate catalog (Simon+, 2006)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/641/389https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/641/389http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/641/389https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/641/389https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/641/389http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/641/389GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/641/389/table2 (Properties of the IRDCs)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/641/389/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/641/389/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/641/389/table2?GETtext/xml+votable180.050000true274.424167-15.8274170.005555555555555556Cone search capability for table J/ApJ/641/389/table3 (Properties of the IRDC cores)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/641/389/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/641/389/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/641/389/table3?GETtext/xml+votable180.050000true274.46-15.8938890.0055555555555555566/29118 29508 29510 29529 29532 29533 29535 30218 30245 30256 30258 30262 30263 30312 30315 30318 30319 30330 30417 30421 30692 30716https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/641/389?format=asciiInfraredRadiodefaultJ/ApJ/641/389/table2Properties of the IRDCsMassEstimated masssolMassphys.massintrecnoRecord number assigned by the VizieR team.
