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 …

Active galactic nuclei (AGN) are energetic astrophysical sources powered by accretion onto
supermassive black holes in galaxies, and present unique observational signatures that …

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 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 …

A sample of 18 286 radio-loud active galactic nuclei (AGN) is presented, constructed by
combining the seventh data release of the Sloan Digital Sky Survey with the NRAO (National …

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 …

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 …

We present a new semi-analytic model that self-consistently traces the growth of
supermassive black holes (BH) and their host galaxies within the context of the Lambda cold …
