On the distance to the black hole X-ray binary Swift J1727.81613

Benjamin J. Burridge, James C. A. Miller-Jones, Arash Bahramian +11

We review the existing distance estimates to the black hole X-ray binary Swift J1727.81613, present new radio and near-UV spectra to update the distance constraints, and discuss…

XRISM reveals a variable, multi-phase outflow-inflow structure during the X-ray obscured 2024 outburst of the black hole transient V4641 Sgr

Maxime Parra, Megumi Shidatsu, Ryota Tomaru +23

We report the results of a simultaneous X-ray and optical spectroscopy campaign on the Galactic black hole X-ray binary V4641 Sgr, carried out with XRISM and the Seimei telescope d…

The peculiar hard state behaviour of the black hole X-ray binary Swift J1727.81613

A. K. Hughes, F. Carotenuto, T. D. Russell +37

Tracking the correlation between radio and X-ray luminosities during black hole X-ray binary outbursts is a key diagnostic of the coupling between accretion inflows (traced by X-ra…

The Accretion-Ejection Connection in the Black Hole X-ray Binary MAXI J1820070

Joe S. Bright, Rob Fender, David M. Russell +12

The black hole X-ray binary MAXI J1820070 began its first recorded outburst in March 2018, and remained an active radio, X-ray, and optical source for over four years. Due to th…

Type I X-ray Burst Emission Reflected into the Eclipses of EXO 0748-676

Amy H. Knight, Jakob van den Eijnden, Adam Ingram +8

The neutron star X-ray binary, EXO 0748--676, was observed regularly by the Rossi X-ray Timing Explorer (RXTE) and XMM-Newton during its first detected outburst (1985 - 2008). Thes…

Peculiar radio-bright behaviour of the Galactic black hole transient 4U 1543-47 in the 2021-2023 outburst

X. Zhang, W. Yu, F. Carotenuto +8

Correlated behaviours between the radio emission and the X-ray emission in Galactic black hole X-ray binaries (BH XRBs) in the X-ray hard state are crucial to the understanding of…
