cds-question@unistra.frmolecular-cloudsmagellanic-cloudsmilky-way-galaxyradio-astronomyWe use high spatial resolution observations of CO to systematically measure the resolved size-line width, luminosity-line width, luminosity-size, and mass-luminosity relations of GMCs in a variety of extragalactic systems. Although the data are heterogeneous, we analyze them in a consistent manner to remove the biases introduced by limited sensitivity and resolution, thus obtaining reliable sizes, velocity dispersions, and luminosities. We compare the results obtained in dwarf galaxies with those from the Local Group spiral galaxies. We find that extragalactic GMC properties measured across a wide range of environments are very much compatible with those in the Galaxy. The property that shows the largest variability is their resolved brightness temperature, although even that is similar to the average Galactic value in most sources.2008ApJ...686..948Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/686/948CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/iram : Plateau de Bure Interferometer Observation Log (IRAM 1991-2010)J/ApJS/178/56 : CO observations of LMC Giant Molecular clouds (Fukui+, 2008)J/ApJ/654/240 : Giant molecular clouds in M31 (Rosolowsky+, 2007)J/ApJ/661/830 : Giant molecular clouds of M33 (Rosolowsky+, 2007)J/ApJS/149/343 : Giant molecular clouds in M33 (Engargiola+, 2003)J/PASJ/53/971 : CO catalog of LMC molecular clouds (Mizuno+, 2001)J/A+AS/115/439 : CO survey of galaxies (Elfhag+, 1996)J/A+AS/116/157 : SEST obs. of extragalactic radiosources (Tornikoski+, 1996)J/A+A/295/585 : CO observations in NGC 1365 (Sandqvist+, 1995)J/A+A/276/25 : ESO-SEST Key Program on CO in LMC and SMC (Israel+ 1993)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/686/948https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/686/948http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/686/948https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/686/948https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/686/948http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/686/948GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/686/948/table3 (Radio observations)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/686/948/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/686/948/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/686/948/table3?GETtext/xml+votable180.050000true9.73548.3388610.005555555555555556Cone search capability for table J/ApJ/686/948/table1 (Data sets used in this paper)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/686/948/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/686/948/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/686/948/table1?GETtext/xml+votable180.050000true5.096559.29297220.0055555555555555566/2155 2241 2623 2709 2774 3042 3389 7602 7604 10911 11227 28631 33091 33094 33295 33298 33304 33316https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/686/948?format=asciiRadiodefaultJ/ApJ/686/948/table3Radio observationsGalGalaxy observedsrc.class.starGalaxycharTBPeak cloud brightness temperatureKphys.temperature;stat.maxfloatrecnoRecord number assigned by the VizieR team.
