Optical outburst evolution of the transient black hole X-ray binary Swift J1727.8-1613: Disc response to jet ejections and late-outburst emergence of powerful disc winds
N. Castro Segura, K. Solomons, J. M. Corral-Santana +22
Swift J1727.81613 is a newly discovered transient low-mass X-ray binary harbouring a stellar-mass () black hole. We present state-resolved VLT/X-Shooter optical…
Infrared Synchrotron Emission in the Soft State of GX 339-4 and the Mid-Infrared/X-ray Luminosity Plane of Black Hole X-ray Binaries
P. Gandhi, D. M. Russell, M. C. Baglio +33
Progress in understanding the growth of accreting black holes remains hampered by a lack of sensitive coordinated multiwavelength observations. In particular, the mid-infrared (MIR…
Monte-Carlo radiation hydrodynamic simulations of line-driven disc winds: relaxing the isothermal approximation
Amin Mosallanezhad, Christian Knigge, Nicolas Scepi +4
Disc winds play a crucial role in many accreting astrophysical systems across all scales. In accreting white dwarfs (AWDs) and active galactic nuclei (AGN), radiation pressure on s…
Jets from a stellar-mass black hole are as relativistic as those from supermassive black holes
Xian Zhang, Wenfei Yu, Francesco Carotenuto +15
Relativistic jets from supermassive black holes in active galactic nuclei are amongst the most powerful phenomena in the universe, acting to regulate the growth of massive galaxies…
A MeerKAT survey of nearby dwarf novae: I. New detections
J. Kersten, E. Körding, P. A. Woudt +8
A program to search for radio emission from dwarf-novae-type cataclysmic variables was conducted with the South African MeerKAT radio telescope. The dwarf novae RU Pegasi, V426 Oph…
Calibrating the clock of JWST
A. W. Shaw, D. L. Kaplan, P. Gandhi +19
JWST, despite not being designed to observe astrophysical phenomena that vary on rapid time scales, can be an unparalleled tool for such studies. If timing systematics can be contr…
