    Swift J1357.2-0933: the faintest black hole?
    Swift J1357.2-0933 is a confirmed very faint black hole X-ray transient and has a short estimated orbital period of 2.8 h. We observed Swift J1357.2-0933 for...

    SWIFT J1753.5-0127: A Surprising Optical/X-Ray Cross-Correlation Function
    We have conducted simultaneous optical and X-ray observations of SWIFT J1753.5-0127 with RXTE and ULTRACAM, while the system persisted in its relatively bright...

    Swift observations of V404 Cyg during the 2015 outburst: X-ray outflows from super-Eddington accretion
    The black hole (BH) binary V404 Cyg entered the outburst phase in 2015 June after 26 yr of X-ray quiescence, and with its behaviour broke the outburst evolution...

    Swift X-Ray and Ultraviolet Monitoring of the Classical Nova V458 Vul (Nova Vul 2007)
    We describe the highly variable X-ray and UV emission of V458 Vul (Nova Vul 2007), observed by Swift between 1 and 422 days after outburst. Initially bright...

    SWSextantis stars: the dominant population of cataclysmic variables with orbital periods between 3 and 4h
    We present time-series optical photometry of five new cataclysmic variables (CVs) identified by the Hamburg Quasar Survey (HQS). The deep eclipses observed in...

    SY Cnc, a case for unstable mass transfer?
    Intermediate-resolution (0.5-1 Å) optical spectroscopy of the cataclysmic variable (CV) SY Cnc reveals the spectrum of the donor star. Our data enable us to...
