Description
Summary:ABSTRACT We present a list of tailed radio galaxies using the Tata Institute of Fundamental Research (TIFR) Giant Metrewave Radio Telescope (GMRT) Sky Survey Alternative Data Release 1 (TGSS ADR1) at 150 MHz. We visually examined 5336 image fields and found 264 tailed radio galaxies. Tailed radio galaxies are classified as wide-angle tailed (WAT) galaxies or narrow-angle tailed (NAT) galaxies, based on the angle between the two jets of the galaxy. Our sample of tailed radio galaxies included 203 WAT- and 61 NAT-type sources. These newly identified tailed sources are significant additions to the list of known tailed radio galaxies. The source morphology and luminosity features of the various galaxies and their optical identifications are presented. Other radio properties and general features of the sources are also discussed.
