Abstract We present LOw Frequency ARray observations of the Coma Cluster field at 144
MHz. The cluster hosts one of the most famous radio halos, a relic, and a low surface …

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 …

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 …

Radio relics are the manifestation of electrons presumably being shock (re-) accelerated to
high energies in the outskirts of galaxy clusters. However, estimates of the shocks' strength …

Odd radio circles (ORCs) are recently-discovered faint diffuse circles of radio emission, of
unknown cause, surrounding galaxies at moderate redshift (z∼ 0.2–0.6). Here, we present …

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 …

Radio synchrotron emission from the bridges of low-density gas connecting galaxy clusters
and groups is a challenge for particle acceleration processes. In this work, we analyze the …

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 …

The detection of the radio signal from filaments in the cosmic web is crucial to distinguish
possible magnetogenesis scenarios. We review the status of the different attempts to detect …
