The universe's biggest galaxies have both vast atmospheres and supermassive central
black holes. This article reviews how those two components of a large galaxy couple and …

The total mass of a galaxy cluster is one of its most fundamental properties. Together with
the redshift, the mass links observation and theory, allowing us to use the cluster population …

Cosmological simulations are an important theoretical pillar for understanding non-linear
structure formation in our Universe and for relating it to observations on large scales. In …

The hot plasma within merging galaxy clusters is predicted to be filled with shocks and
turbulence that may convert part of their kinetic energy into relativistic electrons and …

In recent years, observations of the Sunyaev-Zeldovich (SZ) effect have had significant
cosmological implications and have begun to serve as a powerful and independent probe of …

The central regions of galaxy clusters are permeated by magnetic fields and filled with
relativistic electrons. When clusters merge, the magnetic fields are amplified and relativistic …

The co-evolution between supermassive black holes and their environment is most directly
traced by the hot atmospheres of dark matter halos. The cooling of the hot atmosphere …

Galaxy clusters are the endpoints of structure formation and are continuously growing
through the merging and accretion of smaller structures. Numerical simulations predict that a …

The fundamental properties of the postulated dark matter (DM) affect the internal structure of
gravitationally bound structures. In the cold dark matter paradigm, DM particles interact only …

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 …
