Extreme particle acceleration in X-ray binaries is linked to their jets

Laura Olivera-Nieto, Fraser J. Cowie, Sera Markoff +2

The detection of multi-TeV radiation from a handful of black-hole X-ray binaries (BHXRBs) has positioned the source class as promising candidate to explain the cosmic-ray flux in t…

Dense, multi-phase accretion disk atmosphere in the low-luminosity state of black hole transientV4641 Sgr

Zuobin Zhang, Rob Fender, James H. Matthews +11

We present soft X-ray spectroscopy of the black-hole X-ray binary V4641~Sgr with the \textit{XMM-Newton} Reflection Grating Spectrometer (RGS). The RGS spectrum shows narrow emissi…

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…

Detection of an Extremely Luminous Radio Counterpart to the Be/X-ray Binary A0538-66

Justine Crook-Mansour, Rob Fender, Alex Andersson +14

We present the discovery of radio emission from the Be/X-ray binary A0538-66 with the Australian Square Kilometre Array Pathfinder (ASKAP), and results from a subsequent weekly mon…

The odyssey of the black hole low mass X-ray binary GX339-4: Five years of dense multi-wavelength monitoring

E. Tremou, S. Corbel, R. Fender +15

We present the longest and the densest quasi-simultaneous radio, X-ray and optical campaign of the black hole low mass X-ray binary GX339-4, covering five years of weekly GX339-4 m…

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…
