Tailed Radio Galaxies from the TIFR GMRT Sky Survey

TL;DR

This paper identifies 264 candidate tailed radio galaxies from the TGSS ADR1 survey at 150 MHz, expanding the catalog of known tailed radio sources and analyzing their properties and classifications.

Contribution

The study provides a new, extensive list of tailed radio galaxy candidates, including morphological and optical data, based on visual examination of a large survey dataset.

Findings

Identified 264 candidate tailed radio galaxies, including 203 WAT and 61 NAT types.

Analyzed morphological and luminosity features of the candidates.

Discussed radio properties and optical identifications of the sources.

Abstract

We present a list of candidate tailed radio galaxies using the TIFR GMRT Sky Survey Alternative Data Release 1 (TGSS ADR1) at 150 MHz. We have visually examined 5336 image fields and found 264 candidates for the tailed galaxy. Tailed radio galaxies are classified as Wide Angle Tailed (WAT) galaxies and Narrow-Angle Tailed (NAT) galaxies, based on the angle between the two jets of the galaxy. We found a sample of tailed radio galaxies which includes 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 different candidate galaxies and their optical identifications are presented in the paper. Other radio properties and general features of the sources are also discussed.
