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.

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 Galaxies at VHE Energies [PDF]
Galaxies, 2018 Radio Galaxies have by now emerged as a new γ-ray emitting source class on the extragalactic sky. Given their remarkable observed characteristics, such as unusual gamma-ray spectra or ultrafast VHE variability, they represent unique examples to probe the

The Host Galaxies and Progenitors of Fast Radio Bursts Localized with the Australian Square Kilometre Array Pathfinder [PDF]
2020 XXXIIIrd General Assembly and Scientific Symposium of the International Union of Radio Science, 2020 The Australian SKA Pathfinder (ASKAP) telescope has started to localize fast radio bursts (FRBs) to arcsecond accuracy from the detection of a single pulse, allowing their host galaxies to be reliably identified.

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.

Giant radio galaxies in the LOFAR Two-metre Sky Survey [PDF]
Astronomy & Astrophysics, 2019 Giant radio galaxies (GRGs) are a subclass of radio galaxies, which have grown to megaparsec scales. GRGs are much rarer than normal-sized radio galaxies (< 0.7 Mpc) and the reason for their gigantic sizes is still debated. Here, we report on the biggest

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 ...

FR0 Radio Galaxies and Their Place in the Radio Morphology Classification [PDF]
Astrophysical Journal, 2018 So-called FR0 radio galaxies have recently emerged as a family of active galaxies with all the same properties as FRI radio galaxies except for their ratio of core to total emission, which is about 30 times higher than that of FRI sources.
