cds-question@unistra.frgalaxy-clustersgalaxiescatalogsradial-velocityApplying an automatic neighbour search algorithm to the 3D UZC galaxy catalogue (Falco et al., 1999, Cat. <J/PASP/111/438>) we have identified 291 compact groups (CGs) with radial velocity between 1000 and 10000km/s. The sample is analysed to investigate whether Triplets display kinematical and morphological characteristics similar to higher order CGs (Multiplets). It is found that Triplets constitute low velocity dispersion structures, have a gas-rich galaxy population and are typically retrieved in sparse environments. Conversely Multiplets show higher velocity dispersion, include few gas-rich members and are generally embedded structures. Evidence hence emerges indicating that Triplets and Multiplets, though sharing a common scale, correspond to different galaxy systems. Triplets are typically field structures whilst Multiplets are mainly subclumps (either temporarily projected or collapsing) within larger structures. Simulations show that selection effects can only partially account for differences, but significant contamination of Triplets by field galaxy interlopers could eventually induce the observed dependences on multiplicity.2002A&A...391...35Fhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/391/35CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/213 : Hickson's Compact groups of Galaxies (Hickson+ 1982-1994)J/PASP/111/438 : Updated Zwicky catalog (UZC) (Falco+, 1999)J/AJ/123/2976 : The UZC-SSRS2 group catalog (Ramella+, 2002)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/391/35https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/391/35http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/391/35https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/391/35https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/391/35http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/391/35GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/391/35/table1 (The Compact groups sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/391/35/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/391/35/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/391/35/table1?GETtext/xml+votable180.050000true0.1791728.395830.005555555555555556Cone search capability for table J/A+A/391/35/table2 (Galaxy members for each Cluster of Galaxy)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/391/35/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/391/35/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/391/35/table2?GETtext/xml+votable180.050000true0.15791728.3844440.0055555555555555566/203 225 745 941 948 953 1677 1680 2129 2131 2134 2214 2216-2217 2229-2230 2236 2251 2254 2276 2641 2750 2790 2830 3419 3441 3564 4105 4108-4110 4188 4212 4214 4301-4302 4322-4323 4349 4352 4360-4361 4446-4447 4469 4519-4520 4552 4577 4599 4650 4698 4720 4753 4756 4806 4816 4870 4891 5075 5078 5149 5241 5244-5245 5247 5282 5288 5413 5558 5634-5635 5640 5724 5773-5774 5797 5799-5800 5824 5891 5903 5918-5919 5925 6047 6087 6090 6093 6104 6138 6216 6370 6376-6377 6663 6668 6777 6780 6944 6968-6969 7030 7036 7042 7159 7198-7199 7265 7267 7308-7309 7324 7479 7485 7522 7584 7597 7688 7693 7704 7708 7770-7771 7842 7896 7898 7925 7947 7975 7979 7982 8067 8110-8111 8203 8225 8228 8315 8318 8328 8339 8345 8367 8391 8418-8419 8495 8506 8654 8728-8729 8759 8763 8839 8919 8938 9052 9126 9132-9133 9406 9429 9433 9624 9946 10210 10220 10350 10364 10366 10394 10398 10471 10520 10531 10594 10628 10894 11026 11071 11104 11114 11129 11132 11234 11253 11255 11306 11314 11327 11389 11391-11392 11394-11395 11434 11653 11664 11699 11710 11776 11791 11936 11947 12001 12004-12006 12016-12017 12210 12438 12444 12461 12471 13380 13511 13529 13543 13550 13693 13894 13901 13903 14893 14979 14983 14994 15174 15887 16114 17661 17761 17866 17975 18008 18013 18055 18071 18103 18195 18217 18219 18279 18285 18290 18407 18901 18934 19104 19315 19321 19483 19538 19624 19900 19918 20031 20060 20213 20220 20222 20284 20309 20332-20333 20386 20392 21875 21976-21978 22361 22994 23296 23835 24027 25853 25972 25975 25981-25982 26041 26043 26046 26055 26060 26072 26102 26175 26181 26191 26231 26253 26261 26264-26265 26268 26385 26388 26396 26403 26422 26500 26563 26584 26961 26963 26987 27086-27087 27098 27107-27109 27199 27203 27206 27314 27340 27343 27365 27470-27471 27479 27560 27562 27634 27722 27727 27736 27738 27759 27770 27800 27803 27811-27812 27814 27853 27855-27856 27868 27872 27874-27875 27924 27926 27945 27948 27998 28075 28146 28162 28168 28249 28251 28278 28294 28300 28365 28377 28436 28458 28463 28494 28515 28574 28596-28597 28611 30044 30070 31222 31228 31338 31405 31407 31430 31436 31998 32175 32183 32226 32340 32460 32479 32540 32545 32548 32550 40946 40952-40954https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/391/35?format=asciiOpticaldefaultJ/A+A/391/35/table1The Compact groups samplerecnoRecord number assigned by the VizieR team.
