cds-question@unistra.frradio-galaxiesco-line-emissionstellar-massesWe present a cross-calibration of CO- and dust-based molecular gas masses at z<=0.2. Our results are based on a survey with the IRAM 30-m telescope collecting CO(1-0) measurements of 78 massive (logM*/M_{sun}_>10) galaxies with known gas-phase metallicities and with IR photometric coverage from Wide-field Infrared Survey Explorer(WISE; 22um) and Herschel Spectral and Photometric Imaging Receiver (SPIRE; 250, 350, 500um). We find a tight relation (~0.17dex scatter) between the gas masses inferred from CO and dust continuum emission, with a minor systematic offset of 0.05dex. The two methods can be brought into agreement by applying a metallicity-dependent adjustment factor (~0.13dex scatter). We illustrate that the observed offset is consistent with a scenario in which dust traces not only molecular gas but also part of the HI reservoir, residing in the H_2_-dominated region of the galaxy. Observations of the CO(2-1) to CO(1-0) line ratio for two-thirds of the sample indicate a narrow range in excitation properties, with a median ratio of luminosities <R_21_>~0.64. Finally, we find dynamical mass constraints from spectral line profile fitting to agree well with the anticipated mass budget enclosed within an effective radius, once all mass components (stars, gas, and dark matter) are accounted for.2018MNRAS.478.1442Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/478/1442CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/311 : WISE All-Sky Data Release (Cutri+ 2012)J/ApJS/210/22 : Herschel Stripe 82 survey (HerS) first catalog (Viero+, 2014)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/478/1442https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/478/1442http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/478/1442https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/478/1442https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/478/1442http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/478/1442GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/478/1442/tableb1 (Directly observable quantities for our 78 Stripe82 galaxies)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/478/1442/tableb1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/478/1442/tableb1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/478/1442/tableb1?GETtext/xml+votable180.050000true26.510417-0.2934170.0055555555555555566/17663 17726 17768 17770 17805 17809-17810 17812 17814 17816-17818 17820-17822 17827-17828 17830-17831 17833 17835 17841 17856 17858 17997-17999 18001 18003-18005 18007 18009-18014 18017 18020 18022-18023 18034 18176-18177https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/478/1442?format=asciiRadiodefaultJ/MNRAS/478/1442/tableb1Directly observable quantities for our 78 Stripe82 galaxiesSimbadNameSimbad column added by the CDSmeta.idcharnullablerecnoRecord number assigned by the VizieR team.
