cds-question@unistra.frradio-galaxiesredshiftedspectroscopyvisible-astronomyWe reported optical spectroscopic observations of X-shaped radio sources with the Hobby-Eberly Telescope and Multiple-Mirror Telescope, focused on the sample of candidates from the FIRST survey presented in Paper I (Cheung, 2007, Cat. <J/AJ/133/2097>). A total of 27 redshifts were successfully obtained, 21 of which are new, including a newly identified candidate source of this type which is presented here. With these observations, the sample of candidates from the previous paper is over 50% spectroscopically identified. Two new broad emission-lined X-shaped radio sources are revealed, while no emission lines were detected in about one-third of the observed sources; a detailed study of the line properties is deferred to a future paper. Finally, to explore their relation to the Fanaroff-Riley division, the radio luminosities and host galaxy absolute magnitudes of a spectroscopically identified sample of 50 X-shaped radio galaxies are calculated to determine their placement in the Owen-Ledlow plane.2009ApJS..181..548Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/181/548CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/133/2097 : FIRST "Winged" & X-shaped radio source candidates (Cheung 2007)J/PASP/97/932 : 3CR Source Identifications (Spinrad+, 1985)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/181/548https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/181/548http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/181/548https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/181/548https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/181/548http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/181/548GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/181/548/table2 (Parameters of spectroscopically identified X-shaped radio galaxy sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/181/548/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/181/548/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/181/548/table2?GETtext/xml+votable180.050000true2.469166712.73472220.0055555555555555566/2186 2899 4119 4835 5048 5267 5694 5808 5930 6482 6595 6957 8557 8927 8989 9010 9351 9851 10585 10675 10726 10770 11116 11496 13120 16120 17407 17517 17719 18009 18014 18113 19052 19664 24304 25523 25566 25849 25914 26202 27195 27577 27825 28069 28293 28484 28626 30140 31333 40944https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/181/548?format=asciiOpticalRadiodefaultJ/ApJS/181/548/table1Observation log and measured redshiftsrecnoRecord number assigned by the VizieR team.
