cds-question@unistra.frradio-sourcespolarimetryA sample of 129 unresolved radio sources with ultrahigh linear polarization (>30%) has been selected from the NRAO VLA Sky Survey. Such high average linear polarization is unusual in extragalactic sources. Higher resolution Australia Telescope Compact Array and Very Large Array observations confirm the high average polarization but find that most of these sources are extended. The Sloan Digital Sky Survey spectroscopy, where available, shows that the optical counterparts are elliptical galaxies with no detectable emission lines. The optical spectra, radio luminosity, linear size and spectral index of these sources are typical of radio-loud active galactic nuclei.2010MNRAS.409..821Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/409/821CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVIII/65 : 1.4GHz NRAO VLA Sky Survey (NVSS) (Condon+ 1998)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/409/821https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/409/821http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/409/821https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/409/821https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/409/821http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/409/821GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/409/821/table1 (The 129 ultrahigh polarization radio sources selected from the NVSS)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/409/821/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/409/821/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/409/821/table1?GETtext/xml+votable180.050000true1.328528.0292777780.005555555555555556Cone search capability for table J/MNRAS/409/821/table2 (High-resolution observations at 1.4GHz with the ATCA, VLA and FIRST survey)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/409/821/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/409/821/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/409/821/table2?GETtext/xml+votable180.050000true59.566875-30.52436110.005555555555555556Cone search capability for table J/MNRAS/409/821/table4 (Optical identifications with the SDSS)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/409/821/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/409/821/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/409/821/table4?GETtext/xml+votable180.050000true114.76812518.073750.0055555555555555566/241 445 518 831 1261 1645 1848 2014 2176 2188 2411 2448 2956 3104 3157 4163 4315 4663 4770 4808 4918 4971 4974 5367 5551 6853 7225 7389 7571 7592 7603 7717 8068 8160 8511 8695 8745 8807 8835 9127 9321 9981 10161 10168 10398 10509 10662 10668 11061 11379 11554 11767 12118 12921 13680 15083 15304 15494 15499 15563 16117 16995 17172 17612 17653 18092 18848 18941 19224 19335 19423 19818 20279 20400 20605 21747 21819 23286 24841 24936 24958 25653 25754 26011 26545 26681 27211 27419 27636 28083 28093 28135 28231 28370 28397 28409 28699 29046 29069 29317 29473 29530 29653 30227 30480 30657 31325 31729 32760 32764 34723 35793 36140 38357 38653 40097 40295 40742 42756 42795 42953 43852 43867 43921 44222 44449 46563 48299 490888.650015785639275e-20 9.710690472292815e-20https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/409/821?format=asciiRadiodefaultJ/MNRAS/409/821/table1The 129 ultrahigh polarization radio sources selected from the NVSSrecnoRecord number assigned by the VizieR team.
