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 …

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 …

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 …

We present deep and high-fidelity images of the merging galaxy cluster A2256 at low
frequencies using the upgraded Giant Metrewave Radio Telescope (uGMRT) and LOw …

We present new LOw-Frequency ARray observations of the massive merging galaxy cluster
MACS J0717. 5+ 3745, located at a redshift of 0.5458. The cluster hosts the most powerful …

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 …

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 …

We simulate the evolution of relativistic electrons injected into the intracluster medium by five
radio galaxies. We study the spatial transport and the emission properties of the injected …

Radio relics are giant (∼ Mpc) synchrotron sources that are believed to be produced by the
(re) acceleration of cosmic ray electrons (CRe) by shocks in the intracluster medium. In this …

Clusters of galaxies have been found to host Mpc-scale diffuse, non-thermal radio emission
in the form of central radio halos and peripheral relics. Turbulence and shock-related …
