“…between these two frequencies. The source is at a redshift of 0.146 (Danziger, Goss and Frater 1978) and the total radio luminosity at 1376 MHz is 2.2 × 10 26 W Hz −1 (herein we adopt cosmological parameters H • = 65 km s −1 Mpc −1 , Ω m = 0.3 and Ω Λ = 0.7). The largest angular size is 12.5 arcmin and we infer the linear size to be 2.1 Mpc.…”

We present ATCA radio observations of the giant radio galaxy J0116−473 at 12 and 22 cm wavelengths in total intensity and polarization. The images clearly reveal a bright inner-double structure within more extended edge-brightened lobe emission. The lack of hotspots at the ends of the outer lobes, the strong core and the inner-double structure with its edge-brightened morphology lead us to suggest that this giant radio galaxy is undergoing a renewed nuclear activity: J0116−473 appears to be a striking example of a radio galaxy where a young double source is evolving within older lobe material. We also report the detection of a Mpc-long linear feature which is oriented perpendicular to the radio axis and has a high fractional polarization.

“…The four largest sources in the sample are 0114-476 (0.95 Mpc), 0211-479 (0.80 Mpc), 0319-454 (1.27 Mpc) and 1308-441 (0.59 Mpc). The first two giants were recognised from previous work Goss 1983 andDanziger et al 1978) and the other two were recognised from my survey with the MOST and the AAT service spectra. If the lowest contour level is used for the angular size then the sizes are greater and 2014-557 must be included since it has diffuse emission with total size around 0.95 Mpc (20 arcmin) but lobes with peaks separated by only 0.27 Mpc (5.7 arcmin) around a strong core.…”

The extended radio source 0319-453 (MSH 03-43) was observed with the Molonglo Observatory Synthesis Telescope as part of a program to study a large sample of southern extragalactic radio sources. The low level structure showed a ridge pointing towards the nearby source 0317-456, which also showed low level structure. It is suggested that the two sources are the asymmetric lobes of a radio galaxy identified with the magnitude 15 peculiar dust-land galaxy AM 0319-452. The galaxy redshift of z = 0.0633 and the radio size of 25.6 arcmin give a projected size of 1.27 Mpc (H = 100 kms−1 Mpc−1). Thus it is one of the largest radio galaxies.

“…G4Jy 619: is a radio galaxy at z = 0.055198 (Storchi-Bergmann et al 1996;Jones et al 2009) also detected in the hard X-rays (Cusumano et al 2010;Oh et al 2018). It is listed in the literature as a giant radio galaxy (Danziger et al 1978;Kronberg et al 2004;Kuźmicz & Jamrozy 2021), and at larger scales it shows a classical FR II radio morphology.…”

Since the early sixties, our view of radio galaxies and quasars has been drastically shaped by discoveries made thanks to observations of radio sources listed in the Third Cambridge Catalog and its revised version (3CR). However, the largest fraction of data collected to date on 3CR sources was performed with relatively old instruments, rarely repeated and/or updated. Importantly, the 3CR contains only objects located in the Northern Hemisphere, thus having limited access to new and innovative astronomical facilities. To mitigate these limitations, we present a new catalog of powerful radio sources visible from the Southern Hemisphere, extracted from the GLEAM 4 Jy (G4Jy) catalog and based on equivalent selection criteria as the 3CR. This new catalog, named G4Jy-3CRE, where the E stands for “equivalent,” lists a total of 264 sources at decl. below −5° and with 9 Jy limiting sensitivity at ∼178 MHz. We explored archival radio maps obtained with different surveys and compared them with optical images available in the Pan-STARRS, DES, and DSS databases to search for optical counterparts of their radio cores. We compared mid-infrared counterparts, originally associated in the G4Jy, with the optical ones identified here, and we present results of a vast literature search carried out to collect redshift estimates for all G4Jy-3CRE sources resulting in a total of 145 reliable z measurements.
