The MIni-Halos in MIni-Clusters (MIMIC) project: New insights into the origin of mini-halos from a LOFAR, uGMRT, and MeerKAT study of diffuse radio emission in Abell 496 and ZwCl 235
F. Ubertosi, S. Giacintucci, A. Botteon +18
We aim at investigating the presence of diffuse radio emission in low-mass (M M), relaxed galaxy clusters. We present a pilot study for the MIMI…
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…
Investigating the magnetic field in the inter-cluster filament between Abell 3667 and Abell 3651 with POSSUM
C. Stuardi, S. P. O'Sullivan, L. Rudnick +19
[Abridged abstract] The objective of this study is to measure the magnetic field within the prominent inter-cluster filament recently detected in X-rays by the extended ROentgen Su…
A "MeerKAT-meets-LOFAR" Study of 2A 0335+096: Discovery of a Complex 500 kpc Radio Halo in a Disturbed Cool-Core Cluster
C. J. Riseley, R. J. van Weeren, L. Lovisari +9
The emerging picture of radio haloes and mini-haloes in galaxy clusters is more blurred and far less distinct than once thought. While both trace cosmic ray electrons and magnetic…
The plethora of diffuse emission in Abell 2034 as revealed by MeerKAT polarization observations
A. Bonafede, M. Balboni, G. W. Pratt +15
We present MeerKAT observations of the galaxy cluster Abell 2034, a massive (M_500=5.21 10^14 solar masses) nearby cluster in a merging state. Previous observations at 144 MHz have…
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…
Galactic Hubs: New Insights and SKA View of AGN Feedback in Galaxy Groups
T. Pasini, M. Brienza, C. J. Riseley
Over the last two decades, significant effort has been devoted to understand the physical processes involved in galaxy evolution. In this context, AGN feedback has emerged as the l…
Magnetic fields at the dawn of structure formation I. The CARLA J1510+5958 proto-cluster
A. Pagliotta, A. Bonafede, C. Stuardi +4
Magnetic fields are a fundamental ingredient of the Universe, influencing the formation and evolution of cosmic structures. While magnetic fields in local galaxy clusters have been…
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…
ASKAP EMU detection of an Odd Radio Circle (ORC) candidate: J094412-751016 (Anglerfish)
M. D. Filipović, Z. J. Smeaton, A. C. Bradley +33
We report diffuse extended radio-continuum emission spatially coinciding with the IR source WISEA J094409.17-751012.8, and a semi-variable star, V687 Carinae. We use 944 MHz radio…
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…
The LOFAR Two-metre Sky Survey: VII. Third Data Release
T. W. Shimwell, M. J. Hardcastle, C. Tasse +99
We present the third data release of the LOFAR Two-metre Sky Survey (LoTSS-DR3). The survey images cover 88% of the northern sky and were created from 12,950 hrs of data (18.6 PB)…
The GLEAM 4-Jy (G4Jy) Sample: III. Further host-galaxy identification, and redshift assessment
Sarah V. White, Precious K. Sejake, Kshitij Thorat +17
In this paper we present 127 new host-galaxy identifications for G4Jy sources (S_151MHz > 4 Jy), based on radio images from MeerKAT, the Very Large Array Sky Survey (VLASS), and th…
