The merging galaxy cluster Abell 3266 at low radio frequencies
S. W. Duchesne, M. Johnston-Hollitt, C. J. Riseley +2
We present new low-frequency (-216 MHz) observations of the complex merging galaxy cluster Abell 3266. These new observations are taken with the Murchison Widefield Array (M…
A broadband radio view of transient jet ejecta in the black hole candidate X-ray binary MAXI J1535-571
J. Chauhan, J. C. A. Miller-Jones, G. E. Anderson +19
We present a broadband radio study of the transient jets ejected from the black hole candidate X-ray binary MAXI J1535-571, which underwent a prolonged outburst beginning on 2 Sept…
Low-frequency integrated radio spectra of diffuse, steep-spectrum sources in galaxy clusters: palaeontology with the MWA and ASKAP
S. W. Duchesne, M. Johnston-Hollitt, I. Bartalucci
Galaxy clusters have been found to host a range of diffuse, non-thermal emission components, generally with steep, power law spectra. In this work we report on the detection and fo…
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…
SPT-CL J2032-5627: a new Southern double relic cluster observed with ASKAP
S. W. Duchesne, M. Johnston-Hollitt, I. Bartalucci +2
We present a radio and X-ray analysis of the galaxy cluster SPT-CL J2032-5627. Investigation of public data from the Australian Square Kilometre Array Pathfinder (ASKAP) at 943 MHz…
