Radio Galaxy Zoo: The Distortion of Radio Galaxies by Galaxy Clusters [PDF]
The Astronomical Journal, 2019 We study the impact of cluster environment on the morphology of a sample of 4304 extended radio galaxies from Radio Galaxy Zoo. A total of 87% of the sample lies within a projected 15 Mpc of an optically identified cluster.

Radio Galaxies at VHE Energies [PDF]
Galaxies, 2018 Radio Galaxies have by now emerged as a new γ-ray emitting source class on the extragalactic sky. Given their remarkable observed characteristics, such as unusual gamma-ray spectra or ultrafast VHE variability, they represent unique examples to probe the

A galactic microquasar mimicking winged radio galaxies [PDF]
Nature Communications, 2017 Winged radio galaxies possess wing features detectable at radio wavelengths, yet the physical interpretation of such extragalactic radio sources remains elusive.

Radio Galaxy Zoo: A Search for Hybrid Morphology Radio Galaxies [PDF]
The Astronomical Journal, 2017 Hybrid morphology radio sources (HyMoRS) are a rare type of radio galaxy that display different Fanaroff–Riley classes on opposite sides of their nuclei.

The Dynamics of Radio Galaxies and Double-Double Radio Galaxies [PDF]
Journal of Astrophysics and Astronomy, 2013 Relativistic and magnetised plasma ejected by radio loud AGNs through jets form the diffuse lobes of radio galaxies. The radiating particles (electron/electron-positron) in lobes emit in radio via the synchrotron process and X-ray via inverse-Compton ...

RADIO SOURCES, GALAXIES, AND CLUSTERS OF GALAXIES [PDF]
Proceedings of the National Academy of Sciences, 1963 The identification of radio sources at high galactic latitudes has progressed to a stage at which it is possible to make the first tentative attempts at a statistical exploration of the results. The identification of the source 3C 48 shows that galactic sources may occur at high galactic latitudes, but the results of the determination of diameters of ...

Radio Galaxy Zoo : host galaxies and radio morphologies derived from visual inspection [PDF]
Monthly Notices of the Royal Astronomical Society, 2015 We present results from the first twelve months of operation of Radio Galaxy Zoo, which upon completion will enable visual inspection of over 170,000 radio sources to determine the host galaxy of the radio emission and the radio morphology.

The Origin and Evolution of Giant Radio Galaxies
Frontiers in Astronomy and Space Sciences, 2022 Giant radio galaxies are arguably the least understood of jetted active galactic nuclei (AGN). We propose that radio galaxies are the product of large mergers that do not involve radio galaxies or radio quasars, such as in merging spiral galaxies, while ...
