FIRST radio galaxy data set containing curated labels of classes FRI, FRII, compact and bent [PDF]
Data in 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 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 ...

Enigmatic Emission Structure around Mrk 783: Cross-Ionization of a Companion 100 kpc Away
Universe, 2023 Mrk 783 is a narrow-line Seyfert 1 galaxy that possesses a relatively large two-sided radio emission extending up to 14 kpc from the active nucleus possibly connected with a large-scale ionized gas emission. We obtained a deep [O iii] image that revealed

Radio Galaxy Zoo: The Distortion of Radio Galaxies by Galaxy Clusters [PDF]
The Astronomical Journal, 2019 Abstract 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. Brightest cluster galaxies (BCGs) are more likely than other cluster members to be radio sources, and are ...

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 ...

Radio Galaxy Zoo: A Search for Hybrid Morphology Radio Galaxies [PDF]
The Astronomical Journal, 2017 Abstract Hybrid morphology radio sources (HyMoRS) are a rare type of radio galaxy that display different Fanaroff–Riley classes on opposite sides of their nuclei. To enhance the statistical analysis of HyMoRS, we embarked on a large-scale search of these sources within the international citizen science project, Radio Galaxy Zoo (RGZ ...
