The central engines of active galactic nuclei (AGNs) are powered by accreting supermassive
black holes, and while AGNs are known to play an important role in galaxy evolution, the key …

Black hole and neutron star X-ray binary systems routinely show quasi-periodic oscillations
(QPOs) in their X-ray flux. Despite being strong, easily measurable signals, their physical …

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 …

We review the properties and behavior of 20 X-ray binaries that contain a dynamically-
confirmed black hole, 17 of which are transient systems. During the past decade, many of …

We present a unified semiquantitative model for the disc–jet coupling in black hole X-ray
binary systems. In the process we have compiled observational aspects from the existing …

We discuss a numerical model for black hole growth and its associated feedback processes
that for the first time allows cosmological simulations of structure formation to self …

Several independent lines of evidence now point to a connection between the physical
processes that govern radio (ie jet) and X-ray emission from accreting X-ray binaries. We …

We review the properties of 40 X-ray binaries that contain either a confirmed black hole or a
black hole candidate. After discussing briefly the significance of these Galactic black holes to …

The hard state of X-ray binaries (XRBs) is characterized by a power-law spectrum in the X-
ray band and a flat/inverted radio/IR spectrum associated with occasionally imaged compact …

We present an analysis of data of the black hole candidate and X-ray transient XTE J1550-
564, taken with the Rossi X-Ray Timing Explorer between 1998 November 22 and 1999 …
