    Evidence for a jet contribution to the optical/infrared light of neutron star X-ray binaries
    Optical/near-infrared (optical/NIR, OIR) light from low-mass neutron star X-ray binaries (NSXBs) in outburst is traditionally thought to be thermal emission...

    Evidence for inflows and outflows in the nearby black hole transient Swift J1727.8−162
    We present 20 epochs of optical spectroscopy obtained with the GTC-10.4m telescope across the bright discovery outburst of the black hole candidate Swift J1727...
  • Publication
    Evidence for mass accretion driven by spiral shocks onto the white dwarf in SDSS J123813.73-033933.0
    We present high-time-resolution photometry and phase-resolved spectroscopy of the short-period ({P_orb}= 80.52 min) cataclysmic variable SDSS J123813.73-033933...

    Evidence for Optical Flares in Quiescent Soft X-Ray Transients
    We present the results of high time resolution optical photometry of five quiescent soft X-ray transients (SXTs): V404 Cyg, A0620-00, J0422+32, GS 2000+25, and...
  • Publication
    Evidence for quiescent synchrotron emission in the black hole X-ray transient Swift J1357.2-0933
    We present high time resolution ULTRACAM optical and NOTCam infrared observations of the edge-on black hole X-ray transient Swift J1357.2-0933. Our data taken...
  • Publication
    Evidence of a Black Hole in the X-Ray Transient GS 1354-64 (=BW Circini)
    We present the first radial velocity curve of the companion star to BW Cir that demonstrates the presence of a black hole in this X-ray transient that recorded...

    Evidence of Magnetic Accretion in an SW Sextantis Star: Discovery of Variable Circular Polarization in LS Pegasi
    We report on the discovery of variable circular polarization in the SW Sextantis star LS Pegasi. The observed modulation has an amplitude of ~0.3% and a period...
  • Publication
    Evidence that short-period AM CVn systems are diverse in outburst behaviour
    We present results of our analysis of up to 15 yr of photometric data from eight AM CVn systems with orbital periods between 22.5 and 26.8 min. Our data have...

    Evolution of the spectral curvature in the ultraluminous X-ray source Holmberg II X-1
    Ultraluminous X-ray sources (ULXs) are interesting systems as they can host intermediate-mass black holes. Alternatively, ULXs can represent stellar mass black...
