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.

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.

arXiv, 2001 Radio spectra of radio galaxies are often ascribed a simple power law form ($S_{\nu} \propto \nu^{\alpha}$) with the spectral index, $\alpha$, being of order -0.7. However, all radio galaxies deviate from this simple power law behaviour. In this paper we derive simple expressions for the average rest-frame spectra of FRI and FRII radio galaxies.

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 ...

On the Encounter between the GASP Galaxy JO36 and the Radio Plume of GIN 049
The Astrophysical Journal, 2023 We report the serendipitous discovery of an unprecedented interaction between the radio lobe of a radio galaxy and a spiral galaxy. The discovery was made thanks to LOFAR observations at 144 MHz of the galaxy cluster A160 ( z = 0.04317) provided by the ...

Host Galaxy Properties and Offset Distributions of Fast Radio Bursts: Implications for Their Progenitors [PDF]
Astrophysical Journal, 2020 We present observations and detailed characterizations of five new host galaxies of fast radio bursts (FRBs) discovered with the Australian Square Kilometre Array Pathfinder (ASKAP) and localized to ≲1″.

The Interplay between Radio AGN Activity and Their Host Galaxies
Galaxies, 2023 Radio activity in AGN (Active Galactic Nuclei) produce feedback on the host galaxy via the impact of the relativistic jets on the circumnuclear gas. Although radio jets can reach up to several times the optical radius of the host galaxy, in this review ...

Radio Galaxy Zoo:Claran– a deep learning classifier for radio morphologies [PDF]
Monthly notices of the Royal Astronomical Society, 2018 The upcoming next-generation large area radio continuum surveys can expect tens of millions of radio sources, rendering the traditional method for radio morphology classification through visual inspection unfeasible. We present CLARAN - Classifying Radio
