Radio Galaxy Zoo: A Search for Hybrid Morphology Radio Galaxies [PDF]
The Astronomical Journal, 2017 Hybrid morphology radio sources (HyMoRS) are a rare type of radio galaxy that display different Fanaroff–Riley classes on opposite sides of their nuclei.

LOFAR discovery of an ultra-steep radio halo and giant head–tail radio galaxy in Abell 1132 [PDF]
, 2017 Low-Frequency Array (LOFAR) observations at 144 MHz have revealed large-scale radio sources in the unrelaxed galaxy cluster Abell 1132. The cluster hosts diffuse radio emission on scales of similar to 650 kpc near the cluster centre and a head-tail (HT ...

Diffuse Radio Emission from Galaxy Clusters [PDF]
Space Science Reviews, 2019 In a growing number of galaxy clusters diffuse extended radio sources have been found. These sources are not directly associated with individual cluster galaxies.

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.

FERMI LARGE AREA TELESCOPE DETECTION OF EXTENDED GAMMA-RAY EMISSION FROM THE RADIO GALAXY FORNAX A [PDF]
, 2016 We report the Fermi Large Area Telescope detection of extended γ-ray emission from the lobes of the radio galaxy Fornax A using 6.1 years of Pass 8 data.

The low density and magnetization of a massive galaxy halo exposed by a fast radio burst [PDF]
Science, 2019 Probing a galaxy halo with a radio burst Fast radio bursts (FRBs) are millisecond flashes of radio emission from distant galaxies. It has only recently become possible to locate single bursts precisely enough to determine the host galaxy. Prochaska et al.

Galaxies, 2018 We study two galaxy clusters with radio relics, 1RXS J0603.3+4214 and RXC J1053.7+5453, through X-ray and radio observations. Radio relics are diffuse non-thermal radio sources found in outskirts of galaxy clusters.

Radio and X-ray Observations of the Restarted Radio Galaxy in the Galaxy Cluster CL 0838+1948
Galaxies, 2021 We present VLA Low-band Ionosphere and Transient Experiment (VLITE) 338 MHz observations of the galaxy cluster CL 0838+1948. We combine the VLITE data with Giant Metrewave Radio Telescope 610 MHz observations and survey data.

A Nonrepeating Fast Radio Burst in a Dwarf Host Galaxy
The Astrophysical Journal, 2023 We present the discovery of an as yet nonrepeating fast radio burst (FRB), FRB 20210117A, with the Australian Square Kilometre Array Pathfinder (ASKAP), as a part of the Commensal Real-time ASKAP Fast Transients Survey.

A radio ridge connecting two galaxy clusters in a filament of the cosmic web [PDF]
Science, 2019 A radio ridge between two galaxy clusters Galaxy clusters contain dozens or hundreds of galaxies, vast quantities of hot gas, and large amounts of dark matter.
