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 …

Diffuse radio emission has been detected in a considerable number of galaxy clusters and
groups, revealing the presence of pervasive cosmic magnetic fields, and of relativistic …

Superclusters are the largest massive structures in the cosmic web, on tens to hundreds of
megaparsec scales. They are the largest assembly of galaxy clusters in the Universe. Apart …

Radio relics are typically found to be arc-like regions of synchrotron emission in the outskirts
of merging galaxy clusters, bowing out from the cluster center. In most cases they show …

The hot intracluster medium (ICM) provides a unique laboratory to test multiscale physics in
numerical simulations and probe plasma physics. Utilizing archival Chandra observations …

Context. Radio relics are megaparsec-sized synchrotron sources located in the outskirts of
some merging galaxy clusters. Binary-merging systems with a favorable orientation may …

Context. Abell 754 is a rich galaxy cluster at z= 0.0543 and is considered the prototype of a
major cluster merger. As many dynamically unrelaxed systems, it hosts diffuse radio …

We present a multiwavelength analysis of 29 merging galaxy clusters that exhibit radio
relics. For each merging system, we perform a weak-lensing analysis on Subaru optical …

Superclusters and galaxy clusters offer a wide range of astrophysical science topics with
regards to studying the evolution and distribution of galaxies, intra-cluster magnetization …

Cosmic rays (CRs) in the shape of relativistic protons and electrons are the source of non-
thermal radiation in a plethora of astrophysical systems. Their emission provides insights …
