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 …

Compact steep-spectrum (CSS) and peaked-spectrum (PS) radio sources are compact,
powerful radio sources. The multi-frequency observational properties and current theories …

We review current understanding of the population of radio galaxies and radio-loud quasars
from an observational perspective, focusing on their large-scale structures and dynamics …

We summarize what large surveys of the contemporary Universe have taught us about the
physics and phenomenology of the processes that link the formation and evolution of …

Radiation, winds, and jets from the active nucleus of a massive galaxy can interact with its
interstellar medium, and this can lead to ejection or heating of the gas. This terminates star …

The radiative cooling timescales at the centers of hot atmospheres surrounding elliptical
galaxies, groups and clusters are much shorter than their ages. Therefore, hot atmospheres …

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 global multidimensional numerical simulations of the plasma that pervades the
dark matter haloes of clusters, groups and massive galaxies (the 'intracluster medium'; ICM) …

Multiwavelength data indicate that the X-ray-emitting plasma in the cores of galaxy clusters
is not cooling catastrophically. To a large extent, cooling is offset by heating due to active …

The relatively recent insight that energy input from supermassive black holes (BHs) can
have a substantial effect on the star formation rates (SFRs) of galaxies motivates us to …
