cds-question@unistra.frgalaxy-clustersredshiftedradial-velocityIn our systematic optical galaxy search behind the southern Milky Way, 3760 (mostly unknown) galaxies with diameters D>0.2' were identified in the Crux region (287{deg}<~l<~318{deg}, |b|<~10{deg}, Woudt & Kraan-Korteweg 1998, in press). Prior to this investigation, only 65 of these galaxies had known redshifts. In order to map the galaxy distribution in redshift space we obtained spectra for 226 bright (B_J_<~18.0mag) objects with the 1.9m telescope of the South African Astronomical Observatory (SAAO). Redshifts could be determined for 209 objects, of which 173 have good signal-to-noise ratios. Of the 36 tentative redshifts, four are confirmed through independent values in the literature. The redshifts of three objects indicate them to be galactic in origin. One of these confirms a suspected Planetary Nebula. For 17 of the galaxies, no redshift could be determined due to poor signal-to-noise ratios. In addition, 26 redshifts have have been measured in the Hydra-Antlia region investigated earlier (Kraan-Korteweg et al., 1995, Cat. <J/A+A/297/617>), of which one is a tentative estimate. Two main structures crossing the Galactic Plane in the Crux region have now become clear. A narrow, nearby filament from (l, b)=(340{deg}, -25{deg}) to the Centaurus cluster can be traced. This filament runs almost parallel to the extension of the Hydra-Antlia clusters found earlier and is part of what we have earlier termed the ``Centaurus Wall'' extending in redshift-space between 0<=v<=6000km/s (Fairall & Paverd 1995, in Wide-Field Spedctroscopy and the Distant Universe, p. 121). The main outcome of this survey however, is the recognition of another massive extended structure between 4000<=v<=8000km/s. This broad structure, dubbed the Norma Supercluster (Woudt et al. 1997, in press), runs nearly parallel to the Galactic Plane from Vela to ACO 3627 (its centre) from where it continues to the Pavo cluster. This massive structure is believed to be associated with the Great Attractor. The survey has furthermore revealed a set of cellular structures, similar to those seen in redshift space at higher galactic latitudes, but never before seen so clearly behind the Milky Way.1998A&AS..127..463Fhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+AS/127/463CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/34 : ESO/Uppsala Survey of the ESO(B) Atlas (Lauberts 1982)J/A+A/297/617 : Hydra/Antlia extension redshifts (I) (Kraan-Korteweg+, 1995)J/A+AS/141/123 : Galaxies behind Southern Milky Way (Kraan-Korteweg 2000)J/A+A/352/39 : Great Attractor region redshifts (III) (Woudt+, 1999)J/A+A/415/9 : Redshifts behind the Southern Milky Way (IV) (Woudt+, 2004)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+AS/127/463https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+AS/127/463http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+AS/127/463https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+AS/127/463https://vizier.iucaa.in/viz-bin/votable?-source=J/A+AS/127/463http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+AS/127/463GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+AS/127/463/table1 (Redshifts of galaxies in the ZOA obtained at the SAAO)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+AS/127/463/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+AS/127/463/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+AS/127/463/table1?GETtext/xml+votable180.050000true154.457304-68.5409110.005555555555555556Cone search capability for table J/A+AS/127/463/table2 (Redshifts of galaxies in the ZOA (Hydra-Antlia region) obtained at the SAAO)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+AS/127/463/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+AS/127/463/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+AS/127/463/table2?GETtext/xml+votable180.050000true129.342671-57.5540180.005555555555555556Cone search capability for table J/A+AS/127/463/table3 (Galaxies observed at the SAAO without reliable redshift)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+AS/127/463/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/A+AS/127/463/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+AS/127/463/table3?GETtext/xml+votable180.050000true163.020088-69.3763190.005555555555555556Cone search capability for table J/A+AS/127/463/table4 (Galaxies in our survey region with velocities from the literature)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+AS/127/463/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/A+AS/127/463/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+AS/127/463/table4?GETtext/xml+votable180.050000true168.284232-69.2666060.0055555555555555565/9316 10299 10770 10776 6/37141 37143 37149-37150 37169 37172 37174-37175 37177 37180 37182 37186 37188-37190 37193-37196 37200-37202 37205 37278 37306 37311 37648 37653-37654 37657 37660 37765 37972-37973 38001-38002 38061 38067 38087 38098 38115 38144-38145 38417 38465 38467 38474 41194 41202-41203 41205 41207-41209 41212-41213 41495 41498 41500-41501 41503 41508 41510-41511 41514 41520 41523-41524 41528 41537-41539 41542 41546 41552-41553 41557 41559 41571-41572 41575 41584 41586 41600 41603 41605-41606 41612-41613 41616 41619 41628 41686 41711 41713 41718 41722 41725-41726 41869 41883 41889-41890 41892 41896 41898-41900 41902 41905-41906 43029 43039 43054 43060 43063-43064 43066-43067 43069 43071 43074 43077-43078 43084-43085 43087 43093 43095-43096 43099 43101-43102 43108-43109 43111 43113-43115 43117-43118 43120-43121 43143 43146-43148 43151 43159-43160 43163-43164 43166 43169 43171 43173 43175 43178-43182 43200-43202 43264-43266 43520-43522https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+AS/127/463?format=asciiOpticaldefaultJ/A+AS/127/463/table1Redshifts of galaxies in the ZOA obtained at the SAAOrecnoRecord number assigned by the VizieR team.
