The LOFAR Two-metre Sky Survey (LoTSS) is an ongoing sensitive, high-resolution 120–
168 MHz survey of the entire northern sky for which observations are now 20% complete …

Context. Relativistic electrons and magnetic fields permeate the intra-cluster medium (ICM)
and manifest themselves as diffuse sources of synchrotron emission observable at radio …

In this article, I review past, current, and future advances on the study of radio-loud AGN
(RLAGN; radio-loud quasars and radio galaxies) lifecycles exclusively in the remnant and …

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 …

Centrally located diffuse radio emission has been observed in both merging and non-
merging galaxy clusters. Depending on their morphology and size, we distinguish between …

Radio haloes and radio relics are diffuse synchrotron sources that extend over Mpc-scales
and are found in a number of merger galaxy clusters. They are believed to form as a …

Diffuse synchrotron radio emission from cosmic ray electrons is observed at the centre of a
number of galaxy clusters. These sources can be classified either as giant radio haloes …

We present results from Low-Frequency Array (LOFAR) and Giant Meterwave Radio
Telescope (GMRT) observations of the galaxy cluster MACS J0717. 5+ 3745. The cluster is …

The propagation of active galactic nucleus jets depends both on the environment into which
they propagate and on their internal structure. To test the impact that different magnetic …

Massive, merging galaxy clusters often host giant, diffuse radio sources that arise from
shocks and turbulence; hence, radio observations can be useful for determining the merger …
