cds-question@unistra.frgalaxy-clustersspectroscopygalaxy-classification-systemsWe present the results of a redshift survey of 138 candidate compact groups from the DPOSS II catalogue, which extends the available redshift range of spectroscopically confirmed compact groups of galaxies to redshift z~0.2. In this survey, we aim to confirm group membership via spectroscopic redshift information, to measure the characteristic properties of the confirmed groups, namely their mass, radius, luminosity, velocity dispersion, and crossing time, and to compare them with those of nearby compact groups. Using information available from the literature, we also studied the surrounding group environment and searched for additional, previously unknown, group members, or larger scale structures to whom the group might be associated.2012A&A...539A.106Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/539/A106CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/125/1660 : Distant compact groups from DPOSS (Iovino+, 2003)J/A+A/445/857 : DPOSS II compact group survey (Pompei+, 2006)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/539/A106https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/539/A106http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/539/A106https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/539/A106https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/539/A106http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/539/A106GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/539/A106/table1 (List of our observed compact groups)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/539/A106/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/539/A106/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/539/A106/table1?GETtext/xml+votable180.050000true2.62437517.83810.0055555555555555566/27 74 96 104 192 200 4179 4185 4359-4361 4363-4364 4428 4443 4453 4480 4496 4536 5216 8208 8223 8246-8247 8309 8334 8408 8542 8561 8614 8695 8783 9019 9296 9360 17807 18216 18742 18778 18802 18830 18843 18850 18872 19020 19023-19025 19030 19035 19038 19057 19200 19213 19237 19244 19257 19290 19322 19467 19484 19872 25839 25855 26094 26185 26189 26192 26258 26271 26298 26302 26327 26333 26342 26370 26418 26438 26453 26460 26492 26502 26508 27066 27082 27087 27127 27132 27213 27224 27236 27261 27346 27355 27382 27411 27417 27496 27507 27528 27533 27540 27561 27571 27657 27662 27722 27724 27736 27746 27763 27771 27859 27869 27880 27969 28004 28174 28276 28311 28321 28333 28345 28432 31371 31388 31390 31413 31419 31424 31437-31438 31479 31627 31662 31739 45052https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/539/A106?format=asciiOpticaldefaultJ/A+A/539/A106/table1List of our observed compact groupsrecnoRecord number assigned by the VizieR team.
