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…
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 …
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 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…
MEDUSA I. Tracing magnetic field structures in tidal arms of the dwarf-dwarf merger NGC 1487
Sam Taziaux, Aritra Basu, Samata Das +11
Dwarf galaxies are important laboratories for studying cosmic magnetism because they can maintain strong magnetic fields via the action of turbulent dynamo despite their low mass a…
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…
Limits on Unintended Radio Emission from Geostationary and Geosynchronous Satellites in the SKA-Low Frequency Range
S. J. Tingay, N. Hurley-Walker, K. Ross +3
We search data from the GLEAM-X survey, obtained with the Murchison Widefield Array (MWA) in 2020, for the presence of radio frequency interference from distant Earth-orbiting sate…
Generating all-sky radio continuum clustering simulations with GHOST
Brandon Venville, Anna Bonaldi, David Parkinson +3
Techniques using multiple tracers of the large scale structure of the universe show great promise for examining the fundamentals of our Universe's cosmology. Such techniques rely o…
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…
CHILLING: Continuum Halos in LVHIS Local Irregular Nearby Galaxies - Radio continuum spectral behavior of dwarf galaxies
Sam Taziaux, Megan C. Johnson, Onic I. Shuvo +13
Dwarf galaxies, due to their shallow gravitational potentials, provide critical environments for studying feedback mechanisms from star formation and its impacts on dwarf galaxy ev…
A long period transient search method for the Murchison Widefield Array
Csanád Horváth, Natasha Hurley-Walker, Samuel J. McSweeney +2
We present an automated search method for radio transients on the minute timescale focused on the emerging long period transients (LPTs) in image-plane radio data. The method is tu…
