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 …

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 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 …

Formation of galaxy clusters corresponds to the collapse of the largest gravitationally bound
overdensities in the initial density field and is accompanied by the most energetic …

Clusters of galaxies, as the largest virialized systems in the Universe, are ideal laboratories
to study the formation and evolution of cosmic structures. The luminous matter of clusters …

We simulate the growth of galaxies and their central supermassive black holes by
implementing a suite of semi-analytic models on the output of the Millennium Run, a very …

The ASTRO-H mission was designed and developed through an international collaboration
of JAXA, NASA, ESA, and the CSA. It was successfully launched on February 17, 2016, and …

Black hole accretion flows can be divided into two broad classes: cold and hot. Whereas
cold accretion flows consist of cool optically thick gas and are found at relatively high mass …

High resolution X-ray spectroscopy of the hot gas in galaxy clusters has shown that the gas
is not cooling to low temperatures at the predicted rates of hundreds to thousands of solar …
