cds-question@unistra.frgalaxy-clustersredshiftedultraviolet-photometryWe present a local sample (z<0.15) of 280 star-forming compact groups (SFCGs) of galaxies identified in the ultraviolet Galaxy Evolution EXplorer (GALEX) All-sky Imaging Survey (AIS). So far, just one prototypical example of SFCG, the Blue Infalling Group, has been studied in detail in the Local Universe. The sample of SFCGs is mainly the result of applying a Friends-of-Friends group finder in the space of celestial coordinates with a maximum linking-length of 1.5 arcmin and choosing groups with a minimum number of four members of bright UV-emitting 17<FUV<20.5 sources (mostly galaxies) from the GALEX/AIS catalogue. The result from the search are 280 galaxy groups composed by 226, 39, 11 and 4 groups of four, five, six and seven bright ultraviolet (UV) members, respectively. Only 59 of these 280 newly identified SFCGs have a previous catalogued group counterpart. Group redshifts are available for at least one member in 75 per cent of the SFCGs, and over 40 per cent of the SFCGs have redshifts measured for two or more galaxies. 26 of the SFCGs appear to be located in the infalling regions of clusters with known redshift. The SFCG sample presents a combination of properties different from the group samples studied up to now, such as low-velocity dispersions (sigma_l-o-s_~120km/s), small crossing-times (H_0_t_c_~0.05) and high star formation content (95 per cent of star-forming galaxies). This points to the SFCGs being in an evolutionary stage distinct from those groups selected in the optical and near-infrared ranges. Once redshifts are obtained to discard interlopers, SFCGs will constitute a unique sample of SFCGs.2015MNRAS.453.1965Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/453/1965CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/453/1965https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/453/1965http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/453/1965https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/453/1965https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/453/1965http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/453/1965GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/453/1965/table1 (SFCG catalogue)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/453/1965/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/453/1965/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/453/1965/table1?GETtext/xml+votable180.050000true0.0955417-22.58711110.005555555555555556Cone search capability for table J/MNRAS/453/1965/table2 (SFCG galaxy catalogue)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/453/1965/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/453/1965/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/453/1965/table2?GETtext/xml+votable180.050000true0.0790833-22.57588890.0055555555555555566/2691 2704 4369 4398 4423 4606 4674 4746 4804 4932 4974 5113 5139 5205 5290 5314 5323 5351 5436 5483 5549 5562 5604 5621 5682 5744 6000 6007 6018 6056 6616 6618 7180 7277 7295 7483 8296 8335 8377 8380 8480 8558 8715 8865 8889 8910 8931 8943 8948 8970 8991 9058 9072 9122-9123 9347 9352-9353 9385 9526 9532 9632 9735 9817 9888 9923 10139 10158 10360 10381 10394 10427 10435 10439 10464-10465 10481 10702-10703 10767 10778 10795 10828 10830 10885 10915-10916 10919 10921 10937 10992 11135 11149 11281 11327 11347 11434 11500 11505 11615 11944 12212 12620 16405 16522 16610 16627 16639 16670 16674 16676 16760 16774 16778 16783 16833 16862 16964 17043 17073 17161 17239 17282 17284 17428 17528 17608 17655 17692 17993 18018 18388 18408 18410 18494 19626 19661 20061 20642 20664-20665 21130 21148 21150 21873 23129 23347 25902-25903 26327 26393 26431 26433 26436 26448 26500 26551 26559 26561 26595 26887 26943 26979 27005 27017 27019 27028 27066 27112 27836 27966 27973 27975 28021 28060 28082 28108 28183 28249 28275 28293 28424-28425 28455 28586 31414 31420 31422 31458 31640 31725 32687 32951 32955 32993 33060 33147 33182 33219 33333 33417 33419 33466 33578 33755 34024 34034 34088 34239 34295 34339 34347-34348 34430 34445 34453 34456 34463 34472 34482 34503 34543 34781 34821 34852 34905-34906 34985 35017 35156 35158 35246 35264 35334 35400 35402 35493-35494 35542 35594 35652 35667 35684 35705 35715 35721 35728 35855 35868 35906 35923 36091 36312 36339 36357 36429 36462 36834 37510 43782 43861 43876 45359 45523 45528 45538 45558 45680 45839 45946 46031 46051 46207 46228 46320 46352 46359 46362 46386 46391 46442 46454 46626 46689 46721 46864 46877 46975 47048 47053 47075 47084 48148 48216 48357 48447 48456 48482https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/453/1965?format=asciiUVdefaultJ/MNRAS/453/1965/table1SFCG cataloguerecnoRecord number assigned by the VizieR team.
