Radio Galaxy Zoo: A Search for Hybrid Morphology Radio Galaxies
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 continuum and far-infrared emission from the galaxies in the Eridanus group
, 2005 The Eridanus galaxies follow the well-known radio-FIR correlation. Majority (70%) of these galaxies have their star formation rates below that of the Milky Way.

Starburst radio galaxies: general properties, evolutionary histories and triggering [PDF]
, 2010 In this paper we discuss the results of a programme of spectral synthesis modelling of a sample of starburst radio galaxies in the context of scenarios for the triggering of the activity and the evolution of the host galaxies.

Dwarf Galaxies with Radio-excess Active Galactic Nuclei in the Very Large Array Sky Survey
The Astrophysical JournalWe present a systematic search for radio active galactic nuclei (AGNs) in dwarf galaxies using recent observations taken by the Very Large Array Sky Survey (VLASS).

The Astrophysical Journal, 2023 Powerful radio sources associated with supermassive black holes are among the most luminous objects in the universe, and are frequently recognized both as cosmological probes and active constituents in the evolution of galaxies.

Very high-resolution radio observations of HzRGs
, 2005 We report on first results of an ongoing effort to image a small sample of high-redshift radio galaxies (HzRGs) with milliarcsecond (mas) resolution, using very-long-baseline interferometry (VLBI) techniques.

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 ...

Dynamics of Powerful Radio Galaxies
Galaxies, 2023 Analytical models describing the dynamics of lobed radio sources are essential for interpretation of the tens of millions of radio sources that will be observed by the Square Kilometre Array and pathfinder instruments. We propose that historical models can be grouped into two classes in which the forward expansion of the radio source is driven by ...

Probing the Impact of Radio-mode Feedback on the Properties of the Cool Circumgalactic Medium
The Astrophysical JournalWe explore the influence of radio-mode feedback on the properties of the cool circumgalactic medium (CGM). To this end, we assemble a statistical sample of approximately 30,000 radio galaxies with background quasars by combining optical spectroscopic ...

The Clustering Of Galaxies Around Radio-Loud AGNs
, 2013 We examine the hypothesis that mergers and close encounters between galaxies can fuel AGNs by increasing the rate at which gas accretes towards the central black hole.
