In a growing number of galaxy clusters diffuse extended radio sources have been found.
These sources are not directly associated with individual cluster galaxies. The radio …

MeerKAT's large number (64) of 13.5 m diameter antennas, spanning 8 km with a densely
packed 1 km core, create a powerful instrument for wide-area surveys, with high sensitivity …

Context. Radio relics in galaxy clusters are giant diffuse synchrotron sources powered in
cluster outskirts by merger shocks. Although the relic–shock connection has been …

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 …

We present deep LOFAR observations between 120 and 181 MHz of the" Toothbrush"(RX
J0603. 3+ 4214), a cluster that contains one of the brightest radio relic sources known. Our …

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 …

We present LOFAR observations of one of the most spectacular objects in the radio sky:
Abell 2255. This is a nearby (z= 0.0806) merging galaxy cluster hosting one of the first radio …

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 …

In this paper, we investigate a situation where relativistic particles are reaccelerated
diffusing across regions of reconnection and magnetic dynamo in super-Alfvenic …

We report L-band VLA observations of 1RXS J0603. 3+ 4214, a cluster that hosts a bright
radio relic, known as the Toothbrush, and an elongated giant radio halo. These new …
