cds-question@unistra.frradio-galaxiesvisible-astronomysloan-photometryA small number of double-lobed radio galaxies (17 from our own census of the literature) show an additional pair of low surface brightness "wings," thus forming an overall X-shaped appearance. Using the VLA FIRST survey database, we are compiling a large sample of winged and X-shaped radio sources for such studies. As a first step toward this goal, an initial sample of 100 new candidate objects of this type are presented in this paper.2007AJ....133.2097Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/133/2097CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJS/181/548 : X-shaped radio sources.
