cds-question@unistra.frsurveysradio-galaxiesredshiftedWe analyse optical and radio properties of radio galaxies detected in the Sloan Digital Sky Survey. The sample of radio sources is selected from the catalogue of Kimball & Ivezic (2008AJ....136..684K) with flux densities at 325, 1400 and 4850MHz, using Westerbork Northern Sky Survey, NRAO VLA Sky Survey and Green Bank 6cm radio surveys and from flux measurements at 74MHz taken from Very Large Array Low-Frequency Sky Survey (Cohen et al. 2006, Cat. VIII/79). We study radio galaxy spectral properties using radio colour-colour diagrams and find that our sample follows a single power law from 74 to 4850MHz.2010MNRAS.406..197Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/406/197CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVIII/79 : The VLA Low-frequency Sky Survey at 74MHz (Cohen+ 2007)J/A+AS/108/79 : Ultra-steep spectrum radiosources (Roettgering+, 1994)J/A+AS/143/303 : Ultra steep spectrum radio sources catalog (De Breuck+ 2000)J/AJ/123/637 : Ultra-steep-spectrum radio sources (De Breuck +, 2002)J/A+A/436/457 : Ultra-steep spectrum radio sources (Gopal-Krishna+, 2005)J/MNRAS/381/341 : MRCR-SUMSS Ultra-steep-spectrum sample (Broderick+ 2007)http://www.sdss.org : SDSS Home Pagehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/406/197https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/406/197http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/406/197https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/406/197https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/406/197http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/406/197GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/406/197/table1 (Sample of ultrasteep spectra (USS) radio sources in the SDSS catalogue with spectroscopic redshifts)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/406/197/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/406/197/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/406/197/table1?GETtext/xml+votable180.050000true111.487833341.38475830.0055555555555555566/4949 5007 5035 5082 5101 5213 5241 5358 5369 5445 5481 5528 5567 5586 5606 5667 5677 5743 5758 5802 5881 5900 5929 5965-5966 5976 6005 6079 6111 6441 6460 6499 6534 6577 6641 6741 7228 7301 7312 7329 7361 7363 7462 9047 9117 9145 9162 9332 9434 9616 9632 9736 9758 9835 9901 9931 9942 9946 10354 10391 10548 10572 10603 10605 10621-10622 10658 10668 10685 10748 10792 10808 10840 10925 10936 11003 11065 11068 11203 11246 11277 11288 11298 11306 11371 11425 11440 11482 11822 28527 28573 28594 28602-28603 28618 28622 28653-28654https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/406/197?format=asciiOpticalRadiodefaultJ/MNRAS/406/197/table1Sample of ultrasteep spectra (USS) radio sources in the SDSS catalogue with spectroscopic redshiftsrecnoRecord number assigned by the VizieR team.
