cds-question@unistra.frgalaxiesultraviolet-astronomyWe have initiated a search for extended ultraviolet disk (XUV-disk) galaxies in the local universe. Here we compare GALEX UV and visible-NIR images of 189 nearby (D<40Mpc) S0-Sm galaxies included in the GALEX Atlas of Nearby Galaxies (Gil de Paz et al. 2007, Cat. J/ApJS/173/185) and present the first catalog of XUV-disk galaxies. We find that XUV-disk galaxies are surprisingly common but have varied relative (UV/optical) extent and morphology. Type 1 objects (>~20% incidence) have structured, UV-bright/optically faint emission features in the outer disk, beyond the traditional star formation threshold. Type 2 XUV-disk galaxies (~10% incidence) exhibit an exceptionally large, UV-bright/optically low surface brightness (LSB) zone having blue UV-K_s_ outside the effective extent of the inner, older stellar population, but not reaching extreme galactocentric distance.2007ApJS..173..538Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/173/538CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/106/530 : Low surface brightness disk galaxies (Bothun+, 1993)J/ApJS/173/185 : GALEX ultraviolet atlas of nearby galaxies (Gil de Paz+, 2007)J/ApJS/173/441 : UV-Luminous galaxies discovered by GALEX (Hoopes+, 2007)J/A+A/478/353 : Structural properties of disk galaxies (Mendez-Abreu+, 2008)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/173/538https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/173/538http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/173/538https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/173/538https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/173/538http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/173/538GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/173/538/table1 (40Mpc Disk Galaxy Sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/173/538/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/173/538/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/173/538/table1?GETtext/xml+votable180.050000true0.929958315.21830560.0055555555555555566/664 2320 2324 4149 4437 4447 4469 5142 5181 5202 5492 5545 5751 5793 6448 6605 6609 6619 6623 6649 7225 7241 7275 7303 7320 7360 7440 7498 7602 7606 7624 7743 7980 8105 8106 8195 8320 8506 9149 9277 9600 9639 10841 10844 10856 10900 10901 10905 10935 10977 10979 11026 11027 11434 11738 11961 12047 13511 13522 16441 16452 16595 16655 16701 17499 17592 17594 17606 17688 17754 17755 18209 18212 18242 18379 18387 18398 19675 20000 20270 20526 20875 21065 24735 25083 25344 25599 25933 25946 25966 26072 26161 26222 26247 26271 26303 26309 27030 27243 27512 27514 27555 27604 27653 27741 27765 27767 27814 27857 27861 27862 27914 27936 27937 27938 27947 28015 28033 28035 28038 28039 28167 28495 28496 28517 28521 28529 33920 33954 33958 34273 34404 34471 34494 34495 34531 34641 35193 35536 35993 36134 36756 36785 36789 36790 36793 36796 38390 38664 38829 38841 43845 43874 43881 46399 46438 46481 46525 46542 46562 46564 46568 46577 46916 46984 47456 48406https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/173/538?format=asciiUVdefaultJ/ApJS/173/538/table140Mpc Disk Galaxy SamplelogSFRLog of star formation rate (3)log(solMass.yr**-1)phys.SFRfloatrecnoRecord number assigned by the VizieR team.
