Understanding the physical mechanisms that control galaxy formation is a fundamental
challenge in contemporary astrophysics. Recent advances in the field of astrophysical …

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 …

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 review the X-ray spectra of the cores of clusters of galaxies. Recent high resolution X-ray
spectroscopic observations have demonstrated a severe deficit of emission at the lowest X …

We present the first results from a very deep Chandra X-ray observation of the core of the
Perseus cluster of galaxies. A pressure map reveals a clear thick band of high pressure …

We present constraints on the mean matter density, Ωm, dark energy density, ΩDE, and the
dark energy equation of state parameter, w, using Chandra measurements of the X-ray gas …

We present an analysis of the energetics and particle content of the lobes of 24 radio
galaxies at the cores of cooling clusters. The radio lobes in these systems have created …

Using Chandra X-ray observations of nine nearby, X-ray luminous elliptical galaxies with
good optical velocity dispersion measurements, we show that a tight correlation exists …

Ongoing and future radio surveys aim to trace the evolution of black hole growth and
feedback from active galactic nuclei (AGNs) throughout cosmic time; however, there remain …
