Scientific paper

A small number of double-lobed radio galaxies are found with an additional pair of extended low surface brightness ``wings'' of emission giving them a distinctive ``X''-shaped appearance. One popular explanation for the unusual morphologies posits that the central supermassive black hole/accretion disk system underwent a recent realignment; in a merger scenario, the active lobes mark the post-merger axis of the resultant system (e.g., Merritt & Ekers 2002). However, this and other interpretations are not well tested on the few (about one dozen) known examples. In part to remedy this deficiency, a large sample of winged and X-shaped radio sources is being compiled for a systematic study. An initial sample of 100 new candidates is described as well as some of the follow-up work being pursued to test the different scenarios.
