This unique shape is mainly caused by the movement of the galaxy within a cluster, during which the radio jets are deflected by the intracluster medium. A combined method, which involves a deep learning-based radio source finder along with visual inspection, has been utilized to search for BTRGs from the Faint Images of the Radio Sky at Twenty cm survey images. Consequently, a catalog of 4876 BTRGs has been constructed, among which 3871 are newly discovered. Based on the classification scheme of the opening angle between the two jets of the galaxy, BTRGs are typically classified as either wide-angle-tail (WAT) sources or narrow-angle-tail (NAT) sources. Our catalog comprises 4424 WATs and 652 NATs. Among these, optical counterparts are identified for 4193 BTRGs. This catalog covers luminosities in the range of 1.91x10^20^<=L_1.4GHz_<=1.45x10^28^W/Hz and redshifts from z=0.0023 to z=3.43. Various physical properties of these BTRGs and their statistics are presented. Particularly, by the nearest neighbor method, we found that 1825 BTRGs in this catalog belong to galaxy clusters reported in literature. 2025ApJS..276...46L https://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/276/46 Catalog Research IsServedBy TAP VizieR generic service IsServedBy Conesearch service related-to VII/4 : Abell and Zwicky Clusters of Galaxies (Abell+ 1974) VII/110 : Rich Clusters of Galaxies (Abell+ 1989) VIII/51 : the FIRST Survey, version 1998Feb (White+ 1998) VIII/59 : the FIRST Survey, version 1999Jul (White+ 1999) VII/250 : The 2dF Galaxy Redshift Survey (2dFGRS) (2dFGRS Team, 1998-2003) VIII/71 : The FIRST Survey Catalog, Version 03Apr11 (Becker+ 2003) VII/233 : 2MASS All-Sky Extended Source Catalog (XSC) (IPAC/UMass, 2003-2006) VII/259 : 6dF galaxy survey final redshift release (Jones+, 2009) VIII/90 : The FIRST Survey Catalog, Version 12Feb16 (Becker+ 2012) VIII/92 : The FIRST Survey Catalog, Version 2014Dec17 (Helfand+ 2015) V/154 : Sloan Digital Sky Surveys (SDSS), Release 16 (DR16) (Ahumada+, 2020) VII/292 : DESI Legacy Imaging Surveys DR8 photometric redshifts (Duncan, 2022) III/286 : APOGEE-2 DR17 final allStar catalog (Abdurro'uf+, 2022) J/ApJ/306/30 : Catalog of distant galaxy clusters (Gunn+, 1986) J/ApJ/569/689 : Distant cluster hunting.
