Radio ghosts: Radio polarimetry study of newly discovered cluster minihalo candidates or radio tailed galaxies

Sam Taziaux, Christopher J. Riseley, Stefan W. Duchesne +5

Extended diffuse radio emission in the central regions of galaxy clusters is commonly associated with non-thermal processes in the intracluster medium (ICM), but its origin and the…

Cosmic-ray electron propagation in the peculiar barred spiral galaxy NGC 2442

Shengtao Wang, Xiaohui Sun, Volker Heesen +13

Face-on spiral galaxies offer a favorable geometry for studying magnetic-field structures and cosmic-ray (CR) propagation because projection effects and structural overlap are redu…

The MWA Interestingly Deep AStrophysical (MIDAS) Survey: Survey Description and First Data Release

S. Paterson, N. Seymour, N. Hurley-Walker +4

We present the deepest MWA survey to date, targeting the GAMA9 and GAMA23 survey fields at 215.68 MHz. With a bandwidth of 30.72 MHz, the two images cover …

An improved view of cosmic-ray transport and the galactic outflow in NGC 253

Shengtao Wang, George Heald, Stefan W. Duchesne +11

The nearly edge-on starburst galaxy NGC 253 exhibits extended multiwavelength halo emission, making it an ideal laboratory for studying disk-halo transport. We present improved ASK…

Bridging the mass gap: Diffuse radio emission in GAMA galaxy groups using EMU and DINGO survey data

Sai Wagh, Tessa Vernstrom, Luke J. M. Davies +11

Diffuse radio emission provides a powerful probe of non-thermal processes in the large-scale structure, yet its properties in galaxy groups remain poorly constrained. Using deep 94…

The Murchison Widefield Array Phase III upgrade: Sensitivity Doubled, Number of Baselines Quadrupled, Flexibility Enhanced, and EoR Observations Optimised

S. J. Tingay, M. Johnston-Hollitt, R. B. Wayth +32

We describe the latest iteration of upgrades (designated Phase III) to the Murchison Widefield Array (MWA), in the fourth paper in a series that covers the evolution of the telesco…

The Rapid ASKAP Continuum Survey VII: Spectra and Polarisation In Cutouts of Extragalactic Sources (SPICE-RACS) Second Data Release -- Unveiling the Magnetised Sky

Alec J. M. Thomson, Timothy J. Galvin, Stefan W. Duchesne +18

We present the second data release (DR2) of Spectra and Polarisation in Cutouts of Extragalactic sources from RACS (SPICE-RACS). SPICE-RACS DR2 is derived from the third low-band e…

Magnetised CGM Gas at z~1 revealed by SPICE-RACS

Sunil Malik, S. P. O'Sullivan, A. J. M. Thomson +17

Magnetic fields are expected to permeate the circumgalactic medium (CGM) of galaxies, yet direct constraints at high redshift remain limited by the lack of high-quality Faraday rot…

GaLactic and Extragalactic All-sky Murchison Widefield Array survey eXtended (GLEAM-X) III: Galactic Plane

S. Mantovanini, N. Hurley-Walker, K. Ross +3

We present the third data release for the Galactic and Extragalactic All-Sky Murchison Widefield Array eXtended (GLEAM-X) survey, covering = 3800 deg2 of the southern Galactic Plan…

The life of central radio galaxies in clusters: AGN-ICM studies of eRASS1 clusters in the ASKAP fields

Angie Veronica, Thomas H. Reiprich, Florian Pacaud +35

The mechanical feedback from the central AGNs can be crucial for balancing the radiative cooling of the intracluster medium at the cluster centre. We aim to understand the relation…

GLEAM-300: The GaLactic and Extragalactic All-sky Murchison Widefield Array (GLEAM) survey at 300 MHz

S. W. Duchesne, J. H. Cook, N. Hurley-Walker +11

In this paper we present a wide-field radio survey at 300 MHz covering the sky from using the Murchison Widefield Array (MWA). Th…

Teleios (G305.4-2.2) -- the mystery of a perfectly shaped new Galactic supernova remnant

Miroslav D. Filipovic, Zachary J. Smeaton, Roland Kothes +35

We present the serendipitous radio-continuum discovery of a likely Galactic supernova remnant (SNR) G305.4-2.2. This object displays a remarkable circular symmetry in shape, making…

Constraints on LIGO/Virgo Compact Object Mergers from Late-time Radio Observations

Ashna Gulati, Tara Murphy, Dougal Dobie +6

We present results from a search for radio afterglows of compact object mergers conducted with the Australian SKA Pathfinder. We used data from four epochs of the Rapid ASKAP Conti…

Radio afterglows from tidal disruption events: An unbiased sample from ASKAP RACS

Akash Anumarlapudi, Dougal Dobie, David L. Kaplan +23

Late-time ( year) radio follow-up of optically-discovered tidal disruption events (TDEs) is increasingly resulting in detections at radio wavelengths, and there is growing ev…

ASKAP reveals the radio tail structure of the Corkscrew Galaxy shaped by its passage through the Abell 3627 cluster

Bärbel S. Koribalski, Stefan W. Duchesne, Emil Lenc +12

Among the bent tail radio galaxies common in galaxy clusters are some with long, collimated tails (so-called head-tail galaxies) shaped by their interactions with the intracluster…
