cds-question@unistra.frradio-galaxiesinterferometrygalaxy-classification-systemsredshiftedBased on the Australia Telescope Low Brightness Survey (ATLBS) we present a sample of extended radio sources and derive morphological properties of faint radio sources. One hundred nineteen radio galaxies form the ATLBS Extended Source Sample (ATLBS-ESS) consisting of all sources exceeding 30" in extent and integrated flux densities exceeding 1mJy. We give structural details along with information on galaxy identifications and source classifications. The ATLBS-ESS, unlike samples with higher flux-density limits, has almost equal fractions of FR-I and FR-II radio galaxies, with a large fraction of the FR-I population exhibiting 3C31-type structures. Significant asymmetry in lobe extents appears to be a common occurrence in the ATLBS-ESS FR-I sources compared with FR-II sources. We present a sample of 22 FR-Is at z>0.5 with good structural information. The detection of several giant radio sources, with size exceeding 0.7Mpc, at z>1 suggests that giant radio sources are not less common at high redshifts. The ESS also includes a sample of 28 restarted radio galaxies.2012ApJS..199...27Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/199/27CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVIII/81 : Sydney University Molonglo Sky Survey (SUMSS V2.1) (Mauch+ 2008)VIII/65 : 1.4GHz NRAO VLA Sky Survey (NVSS) (Condon+ 1998)J/MNRAS/415/1013 : FR II radio galaxies in SDSS (Koziel-Wierzbowska+, 2011)J/MNRAS/402/2792 : 1388MHz ATLBS Low-Brightness Survey (Subrahmanyan+, 2010)J/ApJS/179/306 : Radio galaxy morphologies (Russell+, 2008)J/MNRAS/381/211 : Radio galaxies in the 2SLAQ LRG Survey (Sadler+, 2007)J/ApJS/103/331 : mJy radio sources at 1.4 GHz (Lu+ 1996)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/199/27https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/199/27http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/199/27https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/199/27https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/199/27http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/199/27GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/199/27/table1 (ATLBS (Australia Telescope Low Brightness Survey) Extended Source Sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/199/27/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/199/27/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/199/27/table1?GETtext/xml+votable180.050000true5.54-67.0861940.005555555555555556Cone search capability for table J/ApJS/199/27/table4 (*Candidate halo-type radio sources in the ATLBS-ESS)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/199/27/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/199/27/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/199/27/table4?GETtext/xml+votable180.050000true6.377708-67.1781940.0055555555555555565/8358 8361 6/33421 33422 33423 33425 33426 33427 33428 33430 33436 33443 334569.276497240453405e-25 9.276497240453405e-25https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/199/27?format=asciiOpticalRadiodefaultJ/ApJS/199/27/table1ATLBS (Australia Telescope Low Brightness Survey) Extended Source SamplerecnoRecord number assigned by the VizieR team.
