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 …

We review how the recent increase in X-ray and radio data from black hole and neutron star
binaries can be merged together with theoretical advances to give a coherent picture of the …

Recent X-ray polarimetric data on the prototypical black hole X-ray binary Cyg X-1 from the
Imaging X-ray Polarimetry Explorer present tight constraints on accretion geometry in the …

The focusing optics of NuSTAR have enabled high signal-to-noise ratio spectra to be
obtained from many X-ray bright active galactic nuclei (AGN) and galactic black hole …

We examine the disc—jet connection in stellar mass and supermassive black holes by
investigating the properties of their compact emission in the X-ray and radio bands. We …

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 …

As the luminosity of an accreting black hole drops to a few percent of Eddington, the
spectrum switches from the familiar soft state to a hard state that is well-described by a …

▪ Abstract GRS 1915+ 105—the first stellar-scale, highly relativistic jet source identified—is a
key system for our understanding of the disc-jet coupling in accreting black hole systems …

We present the first systematic study of (non-radio-selected) radio-loud narrow-line Seyfert 1
(NLS1) galaxies. Cross-correlation of the Catalogue of Quasars and Active Nuclei with …
