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.

FIRST radio galaxy data set containing curated labels of classes FRI, FRII, compact and bent. [PDF]
Data Brief, 2023 Automated classification of astronomical sources is often challenging due to the scarcity of labelled training data. We present a data set with a total number of 2158 data items that contains radio galaxy images with their corresponding morphological ...

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.

MRC B0319-454: Probing the large-scale structure with a giant radio galaxy [PDF]
, 2008 We present an investigation of the relationships between the radio properties of a giant radio galaxy MRC B0319-454 and the surrounding galaxy distribution with the aim of examining the influence of intergalactic gas and gravity associated with the large-scale structure on the evolution in 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 ...

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.

LOFAR discovery of a 700-kpc remnant radio galaxy at low redshift [PDF]
, 2015 Remnant radio galaxies represent the final dying phase of radio galaxy evolution, in which the jets are no longer active. Due to their rarity in flux limited samples and the difficulty of identification, this dying phase remains poorly understood and the

CNN architecture comparison for radio galaxy classification [PDF]
, 2021 The morphological classification of radio sources is important to gain a full understanding of galaxy evolution processes and their relation with local environmental properties.
