cds-question@unistra.frgalaxiesgravitational-lensingmillimeter-astronomysubmillimeter-astronomyWe present and study spatially resolved imaging obtained with the Atacama Large Millimeter/submillimeter Array (ALMA) of multiple ^12^CO(J=6-5, 8-7 and 9-8) and two H_2_O(2_02_-1_11_ and 2_11_-2_02_) emission lines and cold dust continuum toward the gravitationally lensed dusty star forming galaxy SPT0346-52 at z=5.656. Using a visibility-domain source-plane reconstruction we probe the structure and dynamics of the different components of the interstellar medium (ISM) in this galaxy down to scales of 1kpc in the source plane. Measurements of the intrinsic sizes of the different CO emission lines indicate that the higher J transitions trace more compact regions in the galaxy. Similarly, we find smaller dust continuum intrinsic sizes with decreasing wavelength, based on observations at rest-frame 130, 300 and 450um. The source shows significant velocity structure, and clear asymmetry where an elongated structure is observed in the source plane with significant variations in their reconstructed sizes. This could be attributed to a compact merger or turbulent disk rotation. The differences in velocity structure through the different line tracers, however, hint at the former scenario in agreement with previous [CII] line imaging results. Measurements of the CO line ratios and magnifications yield significant variations as a function of velocity, suggesting that modeling of the ISM using integrated values could be misinterpreted. Modeling of the ISM in SPT0346-52 based on delensed fluxes indicate a highly dense and warm medium, qualitatively similar to that observed in high redshift quasar hosts.2019A&A...628A..23Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/628/A23CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/628/A23https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/628/A23http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/628/A23https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/628/A23https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/628/A23http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/628/A23GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/628/A23/list (List of datacubes)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/628/A23/list?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/628/A23/list?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/628/A23/list?GETtext/xml+votable180.050000true56.67133-52.083960.0055555555555555566/34312https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/628/A23?format=asciiMillimeterdefaultJ/A+A/628/A23/listList of datacubesNzNumber of slicesmeta.numberintTitleTitle of the FITS filemeta.title;meta.fitsNxNumber of pixels along X-axismeta.numberintrecnoRecord number assigned by the VizieR team.
