We present a catalog of 290 ‘ winged ’ or X-shaped radio galaxies ( XRGs ) extracted from the latest ( 17 Dec. 2014 ) data release of the ‘ Very Large Array Faint Images of the Radio Sky at Twenty centimeter ’ ( VLA FIRST survey ) . We have combined these radio images with their counterparts in the TIFR GMRT sky survey ( TGSS ) at 150 MHz ( TGSS alternative data release , TGSS_ADR1 ) , in an attempt to identify any low surface-brightness radio emission present in these sources . This has enabled us to assemble a sample of 106 ‘ strong ’ XRG candidates and 184 ‘ probable ’ XRG candidates whose XRG designation must be verified by further observations . The present sample of 290 XRG candidates is almost twice as large as the number of XRGs presently known . Twenty-five of our 290 XRG candidates ( 9 ‘ strong ’ and 16 ‘ probable ’ ) are identified as quasars . Double-peaked narrow emission lines are seen in the optical spectra of three of the XRG candidates ( 2 ‘ strong ’ and 1 ‘ probable ’ ) . Nearly 90 % of the sample is located in the FR II domain of the Owen-Ledlow diagram . A few of the strong XRG candidates have a rather flat radio spectrum ( spectral index \alpha flatter than -0.3 ) between 150 MHz and 1.4 GHz , or between 1.4 GHz and 5 GHz . Since this is not expected for lobe-dominated extragalactic radio sources ( like nearly all known XRGs ) , these sources are particularly suited for follow-up radio imaging and near-simultaneous measurement of the radio spectrum .
