Context. Diffuse cluster-scale synchrotron radio emission is discovered in an increasing
number of galaxy clusters in the form of radio haloes, probing the presence of relativistic …

Context. During their lifetimes, galaxy clusters grow through the accretion of matter from the
filaments of the large-scale structure and from mergers with other clusters. These mergers …

Abell 3266 is a massive and complex merging galaxy cluster that exhibits significant
substructure. We present new, highly sensitive radio continuum observations of Abell 3266 …

Many relaxed cool-core clusters host diffuse radio emission on scales of hundreds of
kiloparsecs: mini-haloes. However, the mechanism responsible for generating them, as well …

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 …

Context. Turbulence introduced into the intracluster medium (ICM) through cluster-merger
events transfers energy to non-thermal components, and can trigger the formation of diffuse …

The discovery of diffuse radio emission in galaxy clusters proved the existence of energetic
cosmic-ray electrons and cosmic magnetic fields on Mpc-scales in the Universe …

Abstract El Gordo (ACT-CL J0102-4915) is an extraordinarily large and bright galaxy cluster
collision. In a previous study, we found that El Gordo is in 6.2σ tension with the Λ cold dark …

We present the first detailed analysis of the radio halo in the merging galaxy cluster Abell
2256 using the LOw Frequency ARray, the upgraded Giant Metrewave Radio Telescope …

Context. Diffuse radio emission in galaxy clusters, namely radio halos and radio relics, is
usually associated with merger events. Despite the tremendous advances in observations in …
