cds-question@unistra.frWe have searched for CO lines in a sample of 21 new morphologically determined polar ring galaxies (of which 9 are kinematically confirmed), obtained from a wide search in the Galaxy Zoo project by Moiseev and collaborators. Polar ring galaxies (PRG) are a unique class of objects, tracing special episodes in the galaxy mass assembly: they could be formed through galaxy interaction, merging, but also through accretion from cosmic filaments. Beside, they enable the study of dark matter haloes in 3 dimensions. The polar ring itself is a sub-system rich in gas, where molecular gas is expected, and new stars are formed. Among the sample of 21 PRG, we have detected five CO-rich systems, that can now be followed up with higher spatial resolution. Their average molecular mass is 9.4x10^9^M_{sun}_, and their average gas fraction is 27% of their baryonic mass, with a range from 15 to 43%, implying that they just accreted a large amount of gas. The position of the detected objects in the velocity- magnitude diagram is offset from the Tully-Fisher relation of normal spirals, as was already found for PRG. This work is part of our multi-wavelength project to determine the detailed morphology and dynamics of Polar-Ring galaxies, test through numerical models their formation scenario, and deduce their dark matter content and 3D-shape.2013A&A...554A..11Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/554/A11CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/MNRAS/418/244 : SDSS-based Polar Ring Catalogue (Moiseev+, 2011)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/554/A11https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/554/A11http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/554/A11https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/554/A11https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/554/A11http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/554/A11GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/554/A11/table1 (Basic data for the polar ring galaxy sample, and sizes of the regions observed in CO(1-0) and CO(2-1))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/554/A11/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/554/A11/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/554/A11/table1?GETtext/xml+votable180.050000true118.14329.34713890.0055555555555555566/4426 4509 4519 4635 5502 6084 6223 7197 8939 8945 8956 9180 9533 9782 10869 26373 27801 27861 28536 30041 316592.381800341673347e-19 4.653515163505597e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/554/A11?format=asciiRadiodefaultJ/A+A/554/A11/table1Basic data for the polar ring galaxy sample, and sizes of the regions observed in CO(1-0) and CO(2-1)sp[*] * indicates spectra in subdirectory spmeta.notecharrecnoRecord number assigned by the VizieR team.
