cds-question@unistra.frgalaxiesh-ii-regionsmolecular-cloudsgalaxy-kinematicsWe have observed three luminous infrared galaxy systems (LIRGS) which are pairs of interacting galaxies, with the Galaxy H{alpha} Fabry-Perot system (GH{alpha}FaS) mounted on the 4.2m William Herschel Telescope at the Roque de los Muchachos Observatory, and combined the observations with the Atacama Large Millimeter Array (ALMA) observations of these systems in CO emission to compare the physical properties of the star formation regions and the molecular gas clouds, and specifically the internal kinematics of the star forming regions. We identified 88 star forming regions in the H$\alpha$ emission data-cubes, and 27 molecular cloud complexes in the CO emission data-cubes. The surface densities of the star formation rate and the molecular gas are significantly higher in these systems than in non-interacting galaxies and the Galaxy, and are closer to the surface densities of the star formation rate and the molecular gas of extreme star forming galaxies at higher redshifts. The large values of the velocity dispersion also show the enhanced gas surface density. The HII regions are situated on the {Sigma}_SFR_-{sigma}_v_ envelope, and so are also in virial equilibrium. Since the virial parameter decreases with the surface densities of both the star formation rate and the molecular gas, we claim that the clouds presented here are gravitationally dominated rather than being in equilibrium with the external pressure.2017MNRAS.465.3461Zhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/465/3461CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/465/3461https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/465/3461http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/465/3461https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/465/3461https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/465/3461http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/465/3461GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/465/3461/tablehii (Properties of HII regions (tablea2, part 1))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/465/3461/tablehii?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/465/3461/tablehii?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/465/3461/tablehii?GETtext/xml+votable180.050000true16.945-17.5083890.005555555555555556Cone search capability for table J/MNRAS/465/3461/tablemol (Properties of GMCs (tablea2, part 2))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/465/3461/tablemol?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/465/3461/tablemol?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/465/3461/tablemol?GETtext/xml+votable180.050000true16.94625-17.5074170.005555555555555556Cone search capability for table J/MNRAS/465/3461/list (List of fits files)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/465/3461/list?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/465/3461/list?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/465/3461/list?GETtext/xml+votable180.050000true68.50302-8.57210.0055555555555555566/16755 19283 22721https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/465/3461?format=asciidefaultJ/MNRAS/465/3461/tablehiiProperties of HII regions (tablea2, part 1)recnoRecord number assigned by the VizieR team.
