A MeerKAT-meets-LOFAR Study of MS 1455.0+2232: A 590 kiloparsec 'Mini'-Halo in a Sloshing Cool-Core Cluster
C. J. Riseley, K. Rajpurohit, F. Loi +13
Radio mini-haloes are poorly-understood, moderately-extended diffuse radio sources that trace the presence of magnetic fields and relativistic electrons on scales of hundreds of ki…
A LOFAR view into the stormy environment of the galaxy cluster 2A0335+096
A. Ignesti, G. Brunetti, T. Shimwell +10
Radio observations represent a powerful probe of the physics occurring in the intracluster medium (ICM) because they trace the relativistic cosmic rays in the cluster magnetic fiel…
Deep low-frequency radio observations of Abell 2256 I: The filamentary radio relic
K. Rajpurohit, R. J. van Weeren, M. Hoeft +22
We present deep and high fidelity images of the merging galaxy cluster Abell 2256 at low frequencies, using the upgraded Giant Metrewave Radio Telescope (uGMRT) and LOw-Frequency A…
Turbulent magnetic fields in the merging galaxy cluster MACS J0717.5+3745: polarization analysis
K. Rajpurohit, M. Hoeft, D. Wittor +20
We present wideband polarimetric observations, obtained with the Karl G. Jansky Very Large Array (VLA), of the merging galaxy cluster MACS J0717.5+3745, which hosts one of the most…
The ultra-steep diffuse radio emission observed in the cool-core cluster RX J1720.1+2638 with LOFAR at 54 MHz
N. Biava, F. de Gasperin, A. Bonafede +17
Diffuse radio emission at the centre of galaxy clusters has been observed both in merging clusters on scales of Mpc, called giant radio haloes, and in relaxed systems with a cool-c…
Spectral analysis of spatially-resolved 3C295 (sub-arcsecond resolution) with the International LOFAR Telescope
Etienne Bonnassieux, Frits Sweijen, Marisa Brienza +11
3C295 is a bright, compact steep spectrum source with a well-studied integrated radio spectral energy distribution (SED) from 132 MHz to 15 GHz. However, spatially resolved spectra…
The Evolutionary Map of the Universe Pilot Survey
Ray P. Norris, Joshua Marvil, J. D. Collier +45
We present the data and initial results from the first Pilot Survey of the Evolutionary Map of the Universe (EMU), observed at 944 MHz with the Australian Square Kilometre Array Pa…
Revisiting the Giant Radio Galaxy ESO 422-G028: Part I. Discovery of a neutral inflow and recent star formation in a restarted giant
Henry R. M. Zovaro, Chris J. Riseley, Philip Taylor +4
Giant radio galaxies provide important clues into the life cycles and triggering mechanisms of radio jets. With large-scale jets spanning 1.8 Mpc, ESO 422-G028 () is a g…
Constraining the AGN duty cycle in the cool-core cluster MS 0735.6+7421 with LOFAR data
Nadia Biava, Marisa Brienza, Annalisa Bonafede +6
MS 0735.6+7421 is a galaxy cluster which hosts a central radio galaxy with a very steep spectrum, produced by one of the most powerful known jetted active galactic nuclei (AGN). Th…
Dissecting nonthermal emission in the complex multiple-merger galaxy cluster Abell 2744: Radio and X-ray analysis
K. Rajpurohit, F. Vazza, R. J. van Weeren +14
We present the first deep low frequency radio observations of the massive and highly disturbed galaxy cluster Abell 2744 using the upgraded Giant Metrewave Radio Telescope (uGMRT).…
Early Science from POSSUM: Shocks, turbulence, and a massive new reservoir of ionised gas in the Fornax cluster
C. S. Anderson, G. H. Heald, J. A. Eilek +19
We present the first Faraday rotation measure (RM) grid study of an individual low-mass cluster -- the Fornax cluster -- which is presently undergoing a series of mergers. Exploiti…
The Galactic Faraday rotation sky 2020
Sebastian Hutschenreuter, Craig S. Anderson, Sarah Betti +34
This work gives an update to existing reconstructions of the Galactic Faraday rotation sky by processing almost all Faraday rotation data sets available at the end of the year 2020…
