Monthly Notices of the Royal Astronomical Society, 1999 We present multi-frequency VLA observations of two giant quasars, 0437-244 and 1025-229, from the Molonglo Complete Sample. These sources have well-defined FRII radio structure, possible one-sided jets, no significant depolarization between 1365 and 4935

Wide-Angle-Tail (WAT) Radio Sources
Galaxies, 2023 We review the properties of Wide-Angle-Tail (WAT) radio sources. The WAT radio sources are powerful, bent radio sources typically associated with the dominant galaxy in a cluster or group.

Radio Morphology of Gamma-Ray Sources: Double-lobed Radio Sources
The Astrophysical JournalThe extragalactic γ -ray sky is dominated by relativistic jets aligned to the observer’s line of sight, i.e., blazars. A few of their misaligned counterparts, e.g., radio galaxies, are also detected with the Fermi-Large Area Telescope (LAT), albeit in a ...

Radio Galaxy Zoo: Cosmological Alignment of Radio Sources [PDF]
Monthly Notices of the Royal Astronomical Society, 2017 We study the mutual alignment of radio sources within two surveys, FIRST and TGSS. This is done by producing two position angle catalogues containing the preferential directions of respectively $30\,059$ and $11\,674$ extended sources distributed over ...

Discovery of 178 Giant Radio Galaxies in 1059 deg2 of the Rapid ASKAP Continuum Survey at 888 MHz
Galaxies, 2021 We report the results of a visual inspection of images of the Rapid ASKAP Continuum Survey (RACS) in search of extended radio galaxies (ERG) that reach or exceed linear sizes on the order of one Megaparsec. We searched a contiguous area of 1059 deg2 from

Bent It Like FRs: Extended Radio AGN in the COSMOS Field and Their Large-Scale Environment
Galaxies, 2021 A fascinating topic in radio astronomy is how to associate the complexity of observed radio structures with their environment in order to understand their interplay and the reason for the plethora of radio structures found in surveys. In this project, we

RELICS OF DOUBLE RADIO SOURCES [PDF]
The Astrophysical Journal, 2009 We have formed a new sample which consists of extended extragalactic radio sources without obvious active galactic nuclei (AGN) in them. Most of these sources appear to be dead double radio sources. These sources with steep spectra ($α< $ -1.8; S $\propto ν^α$) were identified using the 74 (VLSS) and the 1400 MHz (NVSS) surveys and further imaged ...

Simulations of Superluminal Radio Sources [PDF]
Monthly Notices of the Royal Astronomical Society, 1996 The superluminal knots of VLBI-sources are widely believed to be shocks travelling along relativistic jets. So far only very simple quasi-one dimensional models have been used to study this phenomenon. Recent progress in numerical methods for relativistic fluid dynamics (Falle & Komissarov 1995) make it possible to carry out much more realistic ...
