The Origin and Evolution of Giant Radio Galaxies
Frontiers in Astronomy and Space Sciences, 2022 Giant radio galaxies are arguably the least understood of jetted active galactic nuclei (AGN). We propose that radio galaxies are the product of large mergers that do not involve radio galaxies or radio quasars, such as in merging spiral galaxies, while ...

Radio Galaxies at TeV Energies
Galaxies, 2022 Unlike blazars, radio galaxies have jets that are misaligned relative to our line-of-sight. This misaligned geometry provides us with a unique view of both the jet and super massive black hole.

A galactic microquasar mimicking winged radio galaxies [PDF]
Nature Communications, 2017 Winged radio galaxies possess wing features detectable at radio wavelengths, yet the physical interpretation of such extragalactic radio sources remains elusive.

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 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.

Simulating the Enrichment of Fossil Radio Electrons by Multiple Radio Galaxies
Galaxies, 2023 We simulate the evolution of relativistic electrons injected into the intracluster medium by five radio galaxies. We study the spatial transport and the emission properties of the injected radio plasma over a ∼5 Gyr period, and the sequence of cooling ...
