cds-question@unistra.frsurveysgalaxiesphotometryhst-photometryThis paper presents the Hubble Ultra Deep Field (HUDF), a 1 million secs exposure of an 11arcmin^2^ region in the southern sky with the Advanced Camera for Surveys on the Hubble Space Telescope using Director's Discretionary Time. The exposure time was divided among four filters, F435W (B435), F606W (V606), F775W (i775), and F850LP (z850), to give approximately uniform limiting magnitudes m_AB_~29 for point sources. The image contains at least 10000 objects, presented here as a catalog, the vast majority of which are galaxies. Visual inspection of the images shows few if any galaxies at redshifts greater than ~4 that resemble present-day spiral or elliptical galaxies. The image reinforces the conclusion from the original Hubble Deep Field that galaxies evolved strongly during the first few billion years in the infancy of the universe. Using the Lyman break dropout method to derive samples of galaxies at redshifts between 4 and 7, it is possible to study the apparent evolution of the galaxy luminosity function and number density.2006AJ....132.1729Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/132/1729CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/258 : Hubble Ultra Deep Field Catalog (UDF) (STScI, 2004)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/132/1729https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/132/1729http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/132/1729https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/132/1729https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/132/1729http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/132/1729GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/132/1729/bvi (B_435_, V_606_ and i_775_ dropout sources (tables 6, 7 and 8 of paper))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/132/1729/bvi?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/132/1729/bvi?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/132/1729/bvi?GETtext/xml+votable180.050000true53.16485-27.827240.0055555555555555566/35935https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/132/1729?format=asciidefaultJ/AJ/132/1729/bviB_435_, V_606_ and i_775_ dropout sources (tables 6, 7 and 8 of paper)imag?
