The Host Galaxies of Hybrid Morphology Radio Sources
Andra Stroe, Victoria Catlett, Jeremy J. Harwood +2
Based on their differing radio morphologies, powerful radio galaxies can be separated into the Fanaroff-Riley I (FR-I) and II (FR-II) classes. Hybrid morphology radio sources (HyMo…
Magnetic field evolution in cosmic filaments with LOFAR data
E. Carretti, S. O'Sullivan, V. Vacca +4
Measuring the magnetic field in cosmic filaments reveals how the Universe is magnetised and the process that magnetised it. Using the Rotation Measures (RM) at 144-MHz from the LoT…
The redshift evolution of extragalactic magnetic fields
Valentin Pomakov, Shane O'Sullivan, Marcus Bruggen +7
Faraday rotation studies of distant radio sources can constrain the evolution and the origin of cosmic magnetism. We use data from the LOFAR Two Metre Sky Survey: Data Release 2 (L…
Radio fossils, relics, and haloes in Abell 3266: cluster archaeology with ASKAP-EMU and the ATCA
C. J. Riseley, E. Bonnassieux, T. Vernstrom +21
Abell 3266 is a massive and complex merging galaxy cluster that exhibits significant substructure. We present new, highly sensitive radio continuum observations of Abell 3266 perfo…
Identifying anomalous radio sources in the EMU Pilot Survey using a complexity-based approach
Gary Segal, David Parkinson, Ray Norris +12
The Evolutionary Map of the Universe (EMU) large-area radio continuum survey will detect tens of millions of radio galaxies, giving an opportunity for the detection of previously u…
GaLactic and Extragalactic All-sky Murchison Widefield Array survey eXtended (GLEAM-X) I: Survey Description and Initial Data Release
Natasha Hurley-Walker, Timothy J. Galvin, Stefan W. Duchesne +15
We describe a new low-frequency wideband radio survey of the southern sky. Observations covering 72 - 231 MHz and Declinations south of have been performed with the Mur…
MeerKAT uncovers the physics of an Odd Radio Circle
Ray P. Norris, J. D. Collier, Roland M. Crocker +14
Odd Radio Circles (ORCs) are recently-discovered faint diffuse circles of radio emission, of unknown cause, surrounding galaxies at moderate redshift ($z ~ 0.2-0.6). Here we presen…
Magnetic field strength in cosmic web filaments
E. Carretti, V. Vacca, S. P. O'Sullivan +8
We used the Rotation Measure (RM) catalogue derived from the LOFAR Two-metre Sky Survey Data Release 2 (LoTSS DR2) at 144-MHz to measure the evolution with redshift of the extragal…
Mysterious Odd Radio Circle near the Large Magellanic Cloud -- An Intergalactic Supernova Remnant?
Miroslav D. Filipović, J. L. Payne, R. Z. E. Alsaberi +48
We report the discovery of J0624-6948, a low-surface brightness radio ring, lying between the Galactic Plane and the Large Magellanic Cloud (LMC). It was first detected at 888 MHz…
Radio footprints of a minor merger in the Shapley Supercluster: From supercluster down to galactic scales
T. Venturi, S. Giacintucci, P. Merluzzi +29
The Shapley Supercluster () contains several tens of gravitationally bound clusters and groups, making it it is an ideal subject for radio studies of…
