cds-question@unistra.frradio-sourcesredshiftedWe present a complete sample of megaparsec-sized double radio sources compiled from the Sydney University Molonglo Sky Survey (SUMSS, Cat. <VIII/70>). Almost complete redshift information has been obtained for the sample. The sample has the following defining criteria: Galactic latitude |b|>12.5{deg}, declination {delta}<-50{deg}, and angular size >5'. All the sources have a projected linear size larger than 0.7Mpc (assuming H_0_=71km/s/Mpc). The sample is chosen from a region of the sky covering 2100{deg}^2^. In this paper we present 843MHz radio images of the extended radio morphologies made using the Molonglo Observatory Synthesis Telescope, higher resolution radio observations of any compact radio structures using the Australia Telescope Compact Array, and low-resolution optical spectra of the host galaxies from the 2.3m Australian National University telescope at Siding Spring Observatory. The sample presented here is the first in the southern hemisphere and significantly enhances the database of known giant radio sources. The giant radio sources with linear size exceeding 0.7Mpc have an abundance of (215Mpc)^-3^ at the sensitivity of the survey. In the low-redshift universe, the survey may be suggesting the possibility that giant radio sources with relict lobes are more numerous than giant sources in which beams from the center currently energize the lobes.2005AJ....130..896Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/130/896CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVIII/70 : Sydney University Molonglo Sky Survey (SUMSS) (Mauch+ 2003)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/130/896https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/130/896http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/130/896https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/130/896https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/130/896http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/130/896GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/130/896/tablea31 (Redshifts and spectral lines in spectra in Fig. 29 (tables A1 and A3 of the paper))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/130/896/tablea31?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/130/896/tablea31?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/130/896/tablea31?GETtext/xml+votable180.050000true5.180417-73.3574720.005555555555555556Cone search capability for table J/AJ/130/896/sgrs (Observed and derived properties of the sampleof 18 giant SUMSS radio sources)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/130/896/sgrs?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/130/896/sgrs?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/130/896/sgrs?GETtext/xml+votable180.050000true11.98125-83.13680560.0055555555555555566/32792 32838 32875 32878 32897 33157 33315 33375 33474 33497 34899 37112 37454 37627 39088 41095 41132 41241 45103 45124 45197 45440 45617 45679 46127 46222https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/130/896?format=asciiOpticalRadiodefaultJ/AJ/130/896/tablea31Redshifts and spectral lines in spectra in Fig. 29 (tables A1 and A3 of the paper)recnoRecord number assigned by the VizieR team.
