Spectropolarimetric detection of baryonic mass loading in a transient relativistic jet: application to the black hole X-ray binary Swift J1727.81613
A. K. Hughes, R. P. Fender, G. R. Sivakoff +10
Radio emission during X-ray binary outbursts is dominated by synchrotron radiation from relativistic jets, but is usually studied through total-intensity diagnostics such as flux d…
Transforming X-ray Binary Astrophysics with SKA+VLBI
Tao An, Ailing Wang, James C. A. Miller-Jones +6
X-ray binaries (XRBs) are unique laboratories where accretion, jets, strong gravity and magnetic fields can be probed on humanly tractable timescales. The phased SKA-Mid operating…
Accreting Compact Object Binaries with the SKA
Aru Beri, Francesco Carotenuto, Rob P. Fender +4
Accreting binary systems provide a time-resolved view of the accretion and ejection processes that are seen in all classes of compact objects, from stellar-mass to supermassive. Th…
The link between obscured accretion and mildly relativistic precessing jets
Rob Fender, Sara Motta
We have recently shown evidence that the most relativistic jets (with Lorentz factor >2) from stellar-mass black holes in X-ray binary systems may be locked to a fixed axis, likely…
On The Nature of Einstein Probe Transient EP250916a: Insights from X-ray, Optical, and Radio Observations
Gaurava K. Jaisawal, Giulia Illiano, Francesco Carotenuto +7
We report multi-wavelength studies of the transient EP250916a, detected by the Einstein Probe on 2025 September 16. Located at low Galactic latitude, the source exhibited a rapid X…
The Homogeneous MeerKAT and Swift/XRT X-ray Binary Radio:X-ray Plane
Justine Crook-Mansour, Rob Fender, Andrew Hughes +22
During the hard and quiescent spectral states in X-ray binaries, a non-linear correlation is observed between radio and X-ray luminosities, providing a valuable tool to probe the c…
