With the advent of more sensitive all-sky instruments, the transient universe is being probed
in greater depth than ever before. Taking advantage of available resources, we have …

We use very long baseline interferometry to measure the proper motions of three black hole
X-ray binaries (BHXBs). Using these results together with data from the literature and Gaia …

We compile a catalogue of low-mass and high-mass X-ray binaries, some recently reported
binaries that likely host a neutron star (NS) or a black hole (BH), and binary pulsars (a pulsar …

In this paper, we consider the reported measurements of black hole spin for black hole X-ray
binaries and compare them against the measurements of jet power and speed across all …

We revisit a core prediction of the disc instability model (DIM) applied to X-ray binaries. The
model predicts the existence of a critical mass-transfer rate, which depends on disc size …

XMM–Newton X-ray spectra of the hard state black hole X-ray binaries (BHXRBs) SWIFT
J1753. 5− 0127 and GX 339− 4 show evidence for accretion disc blackbody emission, in …

Stellar mass black holes in the low-hard state may hold clues to jet formation and basic
accretion disc physics, but the nature of the accretion flow remains uncertain. A standard thin …

The black hole X-ray transient MAXI J1820+ 070 (= ASSASN-18ey) discovered in 2018
March was one of the optically brightest ever seen, which has resulted in very detailed …

A rapid timing analysis of Very Large Telescope (VLT)/ULTRACAM (optical) and RXTE (X-
ray) observations of the Galactic black hole binary GX 339− 4 in the low/hard, post-outburst …

MAXI J1659− 152 is a bright X-ray transient black-hole candidate binary system discovered
in September 2010. We report here on MAXI, RXTE, Swift, and XMM-Newton observations …
