cds-question@unistra.frgalaxiesspectroscopyhst-photometryredshiftedWe observed Hubble Deep Field South with the new panoramic integral-field spectrograph MUSE that we built and have just commissioned at the VLT. The data cube resulting from 27h of integration covers one arcmin^2^ field of view at an unprecedented depth with a 1{sigma} emission-line surface brightness limit of 1x10^-19^erg/s/cm2/arcsec2, and contains ~90000 spectra. We present the combined and calibrated data cube, and we performed a first-pass analysis of the sources detected in the Hubble Deep Field South imaging. We measured the redshifts of 189 sources up to a magnitude I_814_=29.5, increasing the number of known spectroscopic redshifts in this field by more than an order of magnitude. We also discovered 26 Ly{alpha} emitting galaxies that are not detected in the HST WFPC2 deep broad-band images. The intermediate spectral resolution of 2.3{AA} allows us to separate resolved asymmetric Ly{alpha} emitters, [OII]3727 emitters, and [CIII]1908 emitters, and the broad instantaneous wavelength range of 4500{AA} helps to identify single emission lines, such as [OIII]5007, H{beta}, and H{alpha}, over a very wide redshift range. We also show how the three-dimensional information of MUSE helps to resolve sources that are confused at ground-based image quality. Overall, secure identifications are provided for 83% of the 227 emission line sources detected in the MUSE data cube and for 32% of the 586 sources identified in the HST catalogue. The overall redshift distribution is fairly flat to z=6.3, with a reduction between z=1.5 to 2.9, in the well-known redshift desert. The field of view of MUSE also allowed us to detect 17 groups within the field. We checked that the number counts of [OII]3727 and Ly{alpha} emitters are roughly consistent with predictions from the literature. Using two examples, we demonstrate that MUSE is able to provide exquisite spatially resolved spectroscopic information on the intermediate-redshift galaxies present in the field. This unique data set can be used for a wide range of follow-up studies. We release the data cube, the associated products, and the source catalogue with redshifts, spectra, and emission-line fluxes.2015A&A...575A..75Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/575/A75CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+AS/145/111 : HDF-South catalogue of galaxies (Volonteri+, 2000)J/AJ/119/486 : HDF-S: STIS imaging (Gardner+, 2000)J/AJ/120/2747 : HDF-South WFPC2 observations (Casertano+, 2000)J/ApJ/538/493 : HDF-South NICMOS field (Yahata+, 2000)J/AJ/122/2190 : HDF-South multicolor observations (Vanzella+, 2001)J/AJ/122/2205 : HDF-South K photometric redshift catalog (Rudnick+, 2001)J/AJ/125/1107 : Ultra-deep near-IR observation in HDF-S (Labbe+, 2003)J/AJ/126/1208 : UVBI magnitudes and redshifts in HDF-South (Sawicki+, 2003)J/A+A/440/61 : FORS spectroscopy of HDFS galaxies (Rigopoulou+, 2005)J/AJ/131/2383 : Photometry and spectroscopy in the HDF-S (Glazebrook+, 2006)J/ApJ/723/1110 : MIPS 24um observations of the HDFS (Huynh+, 2010)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/575/A75https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/575/A75http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/575/A75https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/575/A75https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/575/A75http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/575/A75GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/575/A75/tablea3 (Redshift comparison)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/575/A75/tablea3?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/575/A75/tablea3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/575/A75/tablea3?GETtext/xml+votable180.050000true338.2429167-60.564350.005555555555555556Cone search capability for table J/A+A/575/A75/tablea1 (Basic data and redshifts on sources with spectra in the HDF-S)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/575/A75/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/575/A75/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/575/A75/tablea1?GETtext/xml+votable180.050000true338.2375-60.56825560.0055555555555555566/455262.0401237512456292e-19 1.0405687326842217e-18https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/575/A75?format=asciidefaultJ/A+A/575/A75/tablea3Redshift comparisonrecnoRecord number assigned by the VizieR team.
