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 $…
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…
A LOFAR study of non-merging massive galaxy clusters
Federica Savini, Annalisa Bonafede, Marcus Brueggen +15
Centrally located diffuse radio emission has been observed in both merging and non-merging galaxy clusters. Depending on their morphology and size, we distinguish between giant rad…
The spectacular cluster chain Abell 781 as observed with LOFAR, GMRT, and XMM-Newton
A. Botteon, T. W. Shimwell, A. Bonafede +20
A number of merging galaxy clusters show the presence of large-scale radio emission associated with the intra-cluster medium (ICM). These synchrotron sources are generally classifi…
LOFAR discovery of a double radio halo system in Abell 1758 and radio/X-ray study of the cluster pair
A. Botteon, T. W. Shimwell, A. Bonafede +14
Radio halos and radio relics are diffuse synchrotron sources that extend over Mpc-scales and are found in a number of merger galaxy clusters. They are believed to form as a consequ…
Search for low-frequency diffuse radio emission around a shock in the massive galaxy cluster MACS J0744.9+3927
Amanda Wilber, Marcus Brüggen, Annalisa Bonafede +11
Merging galaxy clusters produce low Mach number shocks in the intracluster medium. These shocks can accelerate electrons to relativistic energies that are detectable at radio frequ…
