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 …

Massive black holes (BHs) are at once exotic and yet ubiquitous, residing at the centers of
massive galaxies in the local Universe. Recent years have seen remarkable advances in …

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 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 …

Collisionless shocks, that is shocks mediated by electromagnetic processes, are customary
in space physics and in astrophysics. They are to be found in a great variety of objects and …

I derive and discuss a simple semi-analytical model of the evolution of powerful radio
galaxies which is not based on assumptions of self-similar growth, but rather implements …

The Fermi Gamma-ray Space Telescope has detected the γ-ray glow emanating from the
giant radio lobes of the radio galaxy Centaurus A. The resolved γ-ray image shows the lobes …

We have performed magnetohydrodynamic (MHD) simulations of relativistic jets from
supermassive blackholes over a few tens of kpc for a range of jet parameters. One of the …

Diffusive shock acceleration is the theory of particle acceleration through multiple shock
crossings. In order for this process to proceed at a rate that can be reconciled with …

We present results from a very deep (650 ks) Chandra X-ray observation of the galaxy group
NGC 5813, the deepest Chandra observation of a galaxy group to date. This system …
