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 ...

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 ...

Radio galaxy zoo EMU: towards a semantic radio galaxy morphology taxonomy [PDF]
Monthly Notices of the Royal Astronomical Society, 2023 ABSTRACT We present a novel natural language processing (NLP) approach to deriving plain English descriptors for science cases otherwise restricted by obfuscating technical terminology. We address the limitations of common radio galaxy morphology classifications by applying this approach.

RADIO DETECTION OF RADIO-QUIET GALAXIES [PDF]
The Astronomical Journal, 2008 We investigate the radio emission of ~185,000 quiescent (optically unclassifiable) galaxies selected from the Sloan Digital Sky Survey (SDSS). By median-stacking FIRST cutouts centered on the optically-selected sources, we are able to reach flux densities down to the 10s of microJy.

Radio galaxies: unification and dust properties [PDF]
New Astronomy Reviews, 2003 The 2002 status of unification models for extragalactic radio sources is examined, with particular emphasis on the dust properties of these objects.

Radio Galaxy Zoo: new giant radio galaxies in the RGZ DR1 catalogue [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT In this paper, we present the identification of five previously unknown giant radio galaxies (GRGs) using Data Release 1 of the Radio Galaxy Zoo citizen science project and a selection method appropriate to the training and validation of deep learning algorithms for new radio surveys.

Radio Galaxies—The TeV Challenge [PDF]
Galaxies, 2018 Over the past decade, our knowledge of the γ -ray sky has been revolutionized by ground- and space-based observatories by detecting photons up to several hundreds of tera-electron volt (TeV) energies. A major population of the γ -ray bright objects are active galactic nuclei (AGN) with their relativistic jets pointed along our line-of-sight ...

The Extended Radio Structures of Quasars and Radio Galaxies [PDF]
Symposium - International Astronomical Union, 1986 We have observed 20 classical double radio galaxies and quasars with MERLIN at 151 MHz. We discuss the systematic variation of the bridge structures with radio power and the nature of the identification.
