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 …

The existence of magnetic fields associated with the intracluster medium in clusters of
galaxies is now well established through different methods of analysis. Magnetic fields are …

We present evidence for the existence of shock waves caused by the formation of the large-
scale structure. In some clusters of galaxies peripherally located sources of extended diffuse …

We use cosmological gas dynamic simulations to investigate the accuracy of galaxy cluster
mass estimates based on X-ray observations. The experiments follow the formation of …

We present the first results of the search of new halo and relic candidates in the NRAO VLA
Sky Survey. We have inspected a sample of 205 clusters from the X-ray-brightest Abell-type …

We investigate the interplay of cosmic ray (CR) propagation and advection in galaxy
clusters. Propagation in form of CR diffusion and streaming tends to drive the CR radial …

The radio sources in the galaxy cluster A3667 have been imaged using the Australia
Telescope Compact Array at both 13 and 20 cm. The most striking source is a large region …

We present a numerical model for the extended steep-spectrum radio sources and the
elongated X-ray structure in A3667 based on new three-dimensional MHD/N-body …

We investigate the generation and distribution of high-energy electrons in the cosmic
structure environment and their observational consequences by carrying out the first …

In several merging clusters of galaxies so-called cluster radio relics have been observed.
These are extended radio sources which do not seem to be associated with any radio …
