It is now established that thermal disc emission and non-thermal jet emission can both play a role at optical/infrared (OIR) wavelengths in X-ray transients...

PublicationA Variable Mid-infrared Synchrotron Break Associated with the Compact Jet in GX 339-4
Many X-ray binaries remain undetected in the mid-infrared, a regime where emission from their compact jets is likely to dominate. Here, we report the detection...

PublicationA VLT-ULTRACAM study of the fast optical quasi-periodic oscillations in the polar V834 Centauri
Quasi-periodic oscillations (QPOs) of a few seconds have been detected in some polars, the synchronised subclass of cataclysmic systems containing a strongly...

PublicationA Wildly Flickering Jet in the Black Hole X-Ray Binary MAXI J1535–571
We report on the results of optical, near-infrared (NIR), and mid-infrared observations of the black hole X-ray binary candidate (BHB) MAXI J1535–571 during its...

PublicationA `high-hard' outburst of the black hole X-ray binary GS 1354-64
We study in detail the evolution of the 2015 outburst of GS 1354-64 (BW Cir) at optical, UV and X-ray wavelengths using Faulkes Telescope South/Las Cumbres...

PublicationAccretion and outflow in V404 Cyg
We study the optical evolution of the 2015 outburst in V404 Cyg, with emphasis on the peculiar nebular phase and subsequent decay to quiescence. From the decay...

PublicationAccretion and UV Variability in BP Tauri
BP Tau is one of the few classical T Tauri stars for which the presence of a hot spot in the surface has been reported without ambiguity. The most likely source...

PublicationAn anticorrelation between X-ray luminosity and Hα equivalent width in X-ray binaries
We report an anticorrelation between continuum luminosity and the equivalent width (EW) of the Hα emission line in X-ray binary systems. The effect is evident...
