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 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 …

Abstract The hot (107 to 108 kelvin), X-ray-emitting intracluster medium (ICM) is the
dominant baryonic constituent of clusters of galaxies. In the cores of many clusters, radiative …

In this paper, we investigate the level of hydrostatic equilibrium (HE) in the intracluster
medium of simulated galaxy clusters, extracted from state-of-the-art cosmological …

The plasma haloes filling massive galaxies, groups and clusters are shaped by active
galactic nucleus (AGN) heating and subsonic turbulence (σ v∼ 150 km s− 1), as probed by …

We present the first results from romulusc, the highest resolution cosmological
hydrodynamic simulation of a galaxy cluster run to date. romulusc, a zoom-in simulation of a …

We propose a novel method to constrain turbulence and bulk motions in massive galaxies,
galaxy groups, and clusters, exploring both simulations and observations. As emerged in the …

We present LOFAR observations of one of the most spectacular objects in the radio sky:
Abell 2255. This is a nearby (z= 0.0806) merging galaxy cluster hosting one of the first radio …

Axions are a viable candidate for cold dark matter, which should generically form minihalos
of subplanetary masses from white-noise isocurvature density fluctuations if the Peccei …

Turbulence is a key ingredient for the evolution of the intracluster medium, whose properties
can be predicted with high-resolution numerical simulations. We present initial results on the …
