A search for giant radio galaxies in recent deep radio surveys

TL;DR

This paper reports the discovery of several new giant radio galaxies (GRGs) using recent deep radio surveys, expanding the known population of these rare, large-scale extragalactic objects.

Contribution

It introduces a new search method applied to recent deep radio surveys, leading to the identification of additional GRGs beyond the previously known 300.

Findings

Several new GRGs discovered in recent surveys

Expanded the catalog of known giant radio galaxies

Demonstrated effectiveness of deep radio survey analysis for rare object detection

Abstract

Giant Radio Galaxies (GRG) are those whose linear size projected on the sky exceeds one Megaparsec (1 Mpc = 3.09e22 m = 3.3 million light years). Since only about 300 of these have been reported in literature, we used two recent deep radio surveys to search for further examples of these rare objects. Here we describe the discovery of several new GRGs in these surveys.
