cds-question@unistra.frgalaxy-clustersultraviolet-photometryvisible-astronomybroad-band-photometryWe analyze three UV images covering a ~100 square degree field toward the Virgo cluster, obtained by the FAUST space experiment. We detect 191 sources to a signal-to-noise ratio of 4.4 and identify 94% of them. Most sources have optical counterparts in existing catalogs, and about half are identified as galaxies. Some sources with no listed counterpart were observed at the Wise Observatory. We present the results of low-resolution visible spectrophotometry and discuss the foreground 101 stellar sources and the 76 detected galaxies, both in the cluster and in the foreground or background. We derive conclusions on star formation properties of galaxies and on the total UV flux from discrete and diffuse sources in the cluster. We test for the presence of intracluster dust, determine the clustering properties of UV emitting galaxies, and derive the UV luminosity function of Virgo galaxies.1997ApJS..111..143Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/111/143CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/48 : Catalogue of middle UV photometry of Virgo cluster galaxiesJ/ApJS/96/461 : Far-UV Point Sources (Bowyer+ 1995)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/111/143https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/111/143http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/111/143https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/111/143https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/111/143http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/111/143GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/111/143/table1 (Detected FAUST sources in the Virgo images)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/111/143/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/111/143/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/111/143/table1?GETtext/xml+votable180.050000true183.03493410.1072110.005555555555555556FAUST5/6929 6931 6932 6933 6937 6941 6943 6976 6978 6985 6990 6/26345 26347 26348 26350 26351 26361 26362 26363 26364 26366 26367 26538 27713 27715 27720 27721 27723 27736 27737 27738 27741 27742 27747 27756 27757 27760 27761 27763 27861 27863 27910 27917 27918 27930 27936 27937 27939 27945 27947 27948 27949 27952 27955 28033 28035 28037 28038 28039 280491.9864425968556103e-21 3.852589004194616e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/111/143?format=asciiUVOpticaldefaultJ/ApJS/111/143/table1Detected FAUST sources in the Virgo imagesrecnoRecord number assigned by the VizieR team.
