cds-question@unistra.frsurveysradial-velocityh-i-line-emissionA blind HI survey of the extragalactic sky behind the southern Milky Way has been conducted with the multibeam receiver on the 64m Parkes radio telescope. The survey covers the Galactic longitude range 212{deg}<l<36{deg} and Galactic latitudes |b|<5{deg} to an rms sensitivity of 6mJy per beam per 27km/s channel and yields 883 galaxies to a recessional velocity of 12000km/s. The survey covers the sky within the HI Parkes All-Sky Survey (HIPASS) area to greater sensitivity, finding lower HI mass galaxies at all distances, and probing more completely the large-scale structures at and beyond the distance of the Great Attractor. Fifty-one percent of the HI detections have an optical/near-infrared (NIR) counterpart in the literature. A further 27% have new counterparts found in existing, or newly obtained, optical/NIR images. The counterpart rate drops in regions of high foreground stellar crowding and extinction, and for low HI mass objects. Only 8% of all counterparts have a previous optical redshift measurement. The HI sources are found independently of Galactic extinction, although the detection rate drops in regions of high Galactic continuum. The survey is incomplete below a flux integral of approximately 3.1Jy/km/s and mean flux density of approximately 21mJy, with 75% and 81% of galaxies being above these limits, respectively. Taking into account dependence on both flux and velocity width, and constructing a scaled dependence on the flux integral limit with velocity width (w^0.74^), completeness limits of 2.8Jy/km/s and 17mJy are determined, with 92% of sources above these limits. A notable new galaxy is HIZOA J1353-58, a possible companion to the Circinus galaxy. Merging this catalog with the similarly conducted northern extension, large-scale structures are delineated, including those within the Puppis and Great Attractor regions and the Local Void. Several newly identified structures are revealed here for the first time. Three new galaxy concentrations (NW1, NW2, and NW3) are key in confirming the diagonal crossing of the Great Attractor Wall between the Norma Cluster and the CIZA J1324.7-5736 cluster. Further contributors to the general mass overdensity in that area are two new clusters (CW1 and CW2) in the nearer Centaurus Wall, one of which forms part of the striking 180{deg} (100h^-1^Mpc) long filament that dominates the southern sky at velocities of ~3000 km/s, and the suggestion of a further wall at the Great Attractor distance at slightly higher longitudes.2016AJ....151...52Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/151/52CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVIII/89 : Northern HI Parkes All Sky Survey Catalogue (HIPASS) (Wong+, 2006)VIII/73 : HI Parkes All Sky Survey Catalogue (HIPASS) (Meyer+, 2004)VII/233 : The 2MASS Extended sources (IPAC/UMass, 2003-2006)II/125 : IRAS catalogue of Point Sources, Version 2.0 (IPAC 1986)J/MNRAS/443/41 : Deep NIR photometry of HI galaxies in ZoA (Williams+, 2014)J/AJ/129/220 : HI Parkes Zone of Avoidance Survey (Donley+, 2005)J/AJ/124/1954 : 1000 brightest HIPASS galaxies catalog (Ryan-Weber+, 2002)J/AJ/124/690 : H I-selected galaxies in South Celestial Cap (Kilborn+, 2002)J/AJ/113/905 : HI observations of galaxies (Pantoja+ 1997)J/A+AS/117/369 : Galaxies in the "zone of avoidance".
