cds-question@unistra.fractive-galactic-nucleiradio-astronomygalaxiesinfrared-sourcessurveysWe present results of a ^12^COJ=3-2 survey of 125 nearby galaxies obtained with the 10m Heinrich Hertz Telescope, with the aim to characterize the properties of warm and dense molecular gas in a large variety of environments. With an angular resolution of 22", ^12^CO3-2 emission was detected in 114 targets. Based on 61 galaxies observed with equal beam sizes the ^12^CO3-2/1-0 integrated line intensity ratio R_31_ is found to vary from 0.2 to 1.9, with an average value of 0.81. No correlations are found for R_31_ to Hubble-type and far-infrared luminosity. Possible indications for a correlation with inclination angle and the 60um/100um color temperature of the dust are not significant. Higher R_31_ ratios than in "normal" galaxies, hinting at enhanced molecular excitation, may be found in galaxies hosting active galactic nuclei. Even higher average values are determined for galaxies with bars or starbursts, the latter being identified by the ratio of infrared luminosity versus isophotal area, log [(L_FIR_/L_{sun}_)/(D^2^_25_/kpc^2^)]>7.25. (U)LIRGs are found to have the highest averaged R_31_ value. This may be a consequence of particularly vigorous star formation activity, triggered by galaxy interaction and merger events.2010ApJ...724.1336Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/724/1336CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/156 : IRAS Faint Source Catalog, |b| > 10, Version 2.0 (Moshir+ 1989)VII/64 : CO Observations of Galaxies (Verter 1985)J/AJ/127/3235 : HIRES atlas of all RBGS galaxies (Surace+, 2004)J/AJ/126/1607 : IRAS Revised Bright Galaxy Sample (Sanders+, 2003)J/A+A/399/1083 : Outer Galaxy IRAS sources and 12CO emission (Kerton+, 2003)J/A+A/411/381 : CO observation of isolated galaxies (Sauty+, 2003)J/ApJS/141/157 : CO (J=1-0) data of cold IRAS sources (Yang+, 2002)J/A+AS/126/3 : CO and HI in interacting galaxies (Horellou+ 1997)J/A+AS/115/439 : CO survey of galaxies (Elfhag+, 1996)J/A+AS/116/193 : CO survey of spirals in Coma supercluster (Casoli+, 1996)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/724/1336https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/724/1336http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/724/1336https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/724/1336https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/724/1336http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/724/1336GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/724/1336/survey (Extragalactic CO(3-2) survey: galaxy sample, and observed properties from the 10m Heinrich Hertz Telescope (HHT))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/724/1336/survey?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/724/1336/survey?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/724/1336/survey?GETtext/xml+votable180.050000true5.11416759.28750.0055555555555555566/650 764 932 1701 2282 2409 3042 3299 3389 3910 4439 4511 5288 5463 5771 5816 5975 5995 6034 6042 6093 6098 7225 7241 7385 7424 7515 7604 7606 7659 7957 8085 8106 8359 8492 8673 8997 9591 9895 10210 10364 10454 10465 10475 10761 10841 10856 10892 10905 10925 10977 11006 11027 11029 11101 11206 11375 11457 11908 13162 13489 13522 15333 15592 17245 17747 17754 17755 18387 18895 18897 19125 19283 20000 20014 22721 22751 25083 25344 25772 25790 26028 26161 26175 26303 26336 26338 26811 27030 27255 27340 27426 27512 27514 27604 27767 27828 27861 27862 27918 27931 28015 28035 28046 28141 28167 28172 28184 28495 28529 28535 29795 31081 31158 36789 40454 43881https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/724/1336?format=asciiInfraredRadiodefaultJ/ApJ/724/1336/surveyExtragalactic CO(3-2) survey: galaxy sample, and observed properties from the 10m Heinrich Hertz Telescope (HHT)SimbadNameSimbad column added by the CDSmeta.idcharl_I32Limit flag on I32meta.code.errorchare_I32?
