Aims. We present new high-sensitivity 153 MHz Giant Meterwave Radio Telescope follow-up observations of the di use steepspectrum cluster radio sources in the galaxy clusters Abell 521, Abell 697, and Abell 1682. Abell 521 hosts a relic, and together with Abell 697 it also hosts a giant very steep-spectrum radio halo. Abell 1682 is a more complex system with candidate steep spectrum di use emission. Methods. We imaged the di use radio emission in these clusters at 153 MHz, and provided flux…

LOFAR discovery of an ultra-steep radio halo and giant head–tail radio galaxy in Abell 1132
Low-Frequency Array (LOFAR) observations at 144 MHz have revealed large-scale radio sources in the unrelaxed galaxy cluster Abell 1132. The cluster hosts diffuse radio emission on scales of similar
Low-frequency integrated radio spectra of diffuse, steep-spectrum sources in galaxy clusters: palaeontology with the MWA and ASKAP
Abstract 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 follow-up of
The Extended GMRT Radio Halo Survey - I. New upper limits on radio halos and mini-halos
Context. A fraction of galaxy clusters host diffuse radio sources called radio halos, radio relics and mini- halos. These are associated with the relativistic electrons and magnetic fields present
Signatures from a merging galaxy cluster and its AGN population: LOFAR observations of Abell 1682
We present LOFAR data from 110–180 MHz of the merging galaxy cluster Abell 1682, alongside archival optical, radio, and X-ray data. Our images of 6 arcsec in resolution at low frequencies reveal new
Diffuse radio emission from galaxy clusters in the LOFAR Two-metre Sky Survey Deep Fields
Low-frequency radio observations are revealing an increasing number of diffuse synchrotron sources from galaxy clusters, primarily in the form of radio halos or radio relics. The existence of this
