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 …

We review theories of dark matter (DM) beyond the collisionless paradigm, known as self-
interacting dark matter (SIDM), and their observable implications for astrophysical structure …

This paper describes the open-source code Enzo, which uses block-structured adaptive
mesh refinement to provide high spatial and temporal resolution for modeling astrophysical …

Radio observations prove the existence of relativistic particles and magnetic field associated
with the intra-cluster-medium (ICM) through the presence of extended synchrotron emission …

We review the present theoretical and numerical understanding of magnetic field
amplification in cosmic large-scale structure, on length scales of galaxy clusters and beyond …

Context. Radio relics in galaxy clusters are giant diffuse synchrotron sources powered in
cluster outskirts by merger shocks. Although the relic–shock connection has been …

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 …

We present deep LOFAR observations between 120 and 181 MHz of the" Toothbrush"(RX
J0603. 3+ 4214), a cluster that contains one of the brightest radio relic sources known. Our …

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 …
