The work in this chapter was published in Cantwell et al. (2016). I personally did all work presented in the paper except the observation and data reducation of the KAT-7 data presented in Sect. 3.2.1 which were carried out by our collaborator N. Oozeer. 

Diffuse radio emission in MACS J0025.4$-$1222: the effect of a major merger on bulk separation of ICM components

Mergers of galaxy clusters are among the most energetic events in the Universe. These events have significant impact on the intra-cluster medium, depositing vast amounts of energy - often in the form

Contribution of Radio Halos to the Foreground for SKA EoR Experiments

The overwhelming foreground contamination is one of the primary impediments to probing the Epoch of Reionization (EoR) through measuring the redshifted 21 cm signal. Among various foreground

A massive cluster at z = 0.288 caught in the process of formation: The case of Abell 959

The largest galaxy clusters are observed still to be forming through major cluster-cluster mergers, often showing observational signatures such as radio relics and giant radio haloes. Using LOFAR

A study of diffuse radio sources and X-ray emission in six massive clusters

The goal of the present study is to extend our current knowledge of the diffuse radio source (halo and relic) populations to $z$ $>$ 0.3. Here we report GMRT and EVLA radio observations of six galaxy

Diffuse radio sources in a statistically complete sample of high-redshift galaxy clusters

Aims. Non-thermal properties of galaxy clusters have been studied using detailed and deep radio images in comparison with X-ray data. While much progress has been made in this area, most of the

Diffuse Radio Emission from Galaxy Clusters

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 emission reveal the

Radio fossils, relics, and haloes in Abell 3266: cluster archaeology with ASKAP-EMU and the ATCA

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 performed with the

Diffuse radio emission in/around the Coma cluster: beyond simple accretion

We report on new 1.41-GHz Green Bank Telescope (GBT) and 352-MHz Westerbork Synthesis Radio Telescope observations of the Coma cluster and its environs. At 1.41 GHz, we tentatively detect an

Using head–tail galaxies to constrain the intracluster magnetic field: an in-depth study of PKS J0334−3900

We present a multi-wavelength study of the radio galaxy PKS J0334-3900 at the centre of Abell 3135. The spectro-polarimetric radio observations are combined with spectroscopic optical and X-ray data

Mass, Light and Colour of the Cosmic Web in the Supercluster SCL2243-0935 (z=0.447)

Aims. In archival 2.2m MPG-ESO/WFI data we discovered several mass peaks through weak gravitational lensing, forming a possible supercluster at redshift 0:45. Through wide-field imaging and

Another shock for the Bullet cluster, and the source of seed electrons for radio relics

ABSTRACT With Australia Telescope Compact Array observations, we detect a highly elongatedMpc-scale diffuse radio source on the eastern periphery of the Bullet cluster 1E0657-55.8,which we argue has

A New Radio-X-Ray Probe of Galaxy Cluster Magnetic Fields

Results are presented of a new VLA-ROSAT study that probes the magnetic field strength and distribution over a sample of 16 "normal" low-redshift (z ≤ 0.1) galaxy clusters. The clusters span 2 orders

EVIDENCE FOR PARTICLE RE-ACCELERATION IN THE RADIO RELIC IN THE GALAXY CLUSTER PLCKG287.0+32.9

Radio relics are diffuse radio sources observed in galaxy clusters, probably produced by shock acceleration during cluster–cluster mergers. Their large size, of the order of 1 Mpc, indicates that the

Bent-Double Radio Sources as Probes of Intergalactic Gas

As the most common environment in the universe, groups of galaxies are likely to contain a significant fraction of the missing baryons in the form of intergalactic gas. The density of this gas is an
