Scalable precision wide-field imaging in radio interferometry: II. AIRI validated on ASKAP data
Amanda G. Wilber, Arwa Dabbech, Matthieu Terris +2
Accompanying Part I, this sequel delineates a validation of the recently proposed AI for Regularisation in radio-interferometric Imaging (AIRI) algorithm on observations from the A…
Scalable precision wide-field imaging in radio interferometry: I. uSARA validated on ASKAP data
Amanda G. Wilber, Arwa Dabbech, Adrian Jackson +1
As Part I of a paper series showcasing a new imaging framework, we consider the recently proposed unconstrained Sparsity Averaging Reweighted Analysis (uSARA) optimisation algorith…
MWA and ASKAP observations of atypical radio-halo-hosting galaxy clusters: Abell 141 and Abell 3404
S. W. Duchesne, M. Johnston-Hollitt, A. G. Wilber
We report on the detection of a giant radio halo in the cluster Abell 3404 as well as confirmation of the radio halo observed in Abell 141 (with linear extents kpc and $…
Radio observations of the merging galaxy cluster system Abell 3391-Abell 3395
M. Brüggen, T. H. Reiprich, E. Bulbul +20
The pre-merging system of galaxy clusters Abell 3391-Abell 3395 located at a mean redshift of 0.053 has been observed at 1 GHz in an ASKAP/EMU Early Science observation as well as…
LOFAR observations of galaxy clusters in HETDEX
R. J. van Weeren, T. W. Shimwell, A. Botteon +20
Diffuse cluster radio sources, in the form of radio halos and relics, reveal the presence of cosmic rays and magnetic fields in the intracluster medium (ICM). These cosmic rays are…
ASKAP reveals giant radio halos in two merging SPT galaxy clusters -- Making the case for a direction-dependent pipeline --
Amanda G. Wilber, Melanie Johnston-Hollitt, Stefan W. Duchesne +4
Early science observations from the Australian Square Kilometre Array Pathfinder (ASKAP) have revealed clear signals of diffuse radio emission associated with two clusters detected…
