cds-question@unistra.frgalaxy-clustersgalaxiesh-i-line-emissionradial-velocityWe investigate the neutral hydrogen (HI) content of 16 groups for which we have multiwavelength data including X-ray observations. Wide-field imaging of the groups was obtained with the 20cm multibeam system on the 64m Parkes telescope. We have detected 10 previously uncatalogued HI sources, one of which has no visible optical counterpart. We examine the HI properties of the groups, compared to their X-ray characteristics, finding that those groups with a higher X-ray temperature and luminosity contain less HI per galaxy.2009MNRAS.400.1962Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/400/1962CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/MNRAS/370/1223 : 15 nearby galaxy groups dynamical properties (Brough+, 2006)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/400/1962https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/400/1962http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/400/1962https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/400/1962https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/400/1962http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/400/1962GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/400/1962/table2 (Summary of the HI observations and results)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/400/1962/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/400/1962/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/400/1962/table2?GETtext/xml+votable180.050000true21.09.43330.005555555555555556Cone search capability for table J/MNRAS/400/1962/tablea (HI detections of the galaxies in groups)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/400/1962/tablea?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/400/1962/tablea?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/400/1962/tablea?GETtext/xml+votable180.050000true21.404120837.978106940.005555555555555556Cone search capability for table J/MNRAS/400/1962/tableb (Optical counterparts to the HI detections)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/400/1962/tableb?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/400/1962/tableb?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/400/1962/tableb?GETtext/xml+votable180.050000true21.39257.990.0055555555555555565/6237 6584 9197 6/17424 17431 17472 17474 17478 17480 18232 18235 18238 18322 18324 18370 18800 18802-18803 18809 18813 19490 24586 24608 24682 24726 24728 24733-24735 24768-24770 24778-24779 24916 24926-24927 24952-24953 24957-24959 25045 25632 25635 25638 25640 25642 26175 26217 26260-26261 26263 26265 26268 26270-26271 26304 26306 26309 26311-26314 26330 26342 33265 33268 33271 33930 33953-33954 33957-33958 33960 33962 33966 34251 34253 34264 34272-34273 34276 36055 36134 36140 36229 36231 36236 36240 36243 36246-36247 36250 36252 36255 36261 36272 36276 36291 36297 36539 36767 36769 36773 36785 36793 36796-36798 38268 38270 38303 38325 38337 38343 38345 38347 38350-38353 38355-38356 38369-38370 38373 38384 46495 46509 46518-46520 46525 46536 46562-46563 46568-46569 46602 46604-46605 46607 46615 46628 46630 46637 46807 46812 46913 46916 46977 46984-46985 46987 46990-46991https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/400/1962?format=asciiOpticalRadiodefaultJ/MNRAS/400/1962/table2Summary of the HI observations and resultsrecnoRecord number assigned by the VizieR team.
