    Infrared spectroscopy of V404 Cygni: limits on the accretion disc contamination
    We have obtained for the first time 2.10-2.45 μm infrared spectra of the soft-X-ray transient V404 Cygni. We determine a 95 per cent confidence upper limit to...

    INTEGRAL observations of the Be/X-ray binary EXO 2030+375 during outburst
    We present a type-I outburst of the high-mass X-ray binary EXO 2030+375, detected during INTEGRAL's Performance and Verification phase in December 2002 (on...

    INTEGRAL observations of the peculiar BeX System SAX J2103.5+4545
    We present an INTEGRAL data analysis of the X-ray transient SAX J2103.5+4545 during two outbursts detected in December 2002. The INTEGRAL coordinates and error...

    Investigating accretion disk - radio jet coupling across the stellar mass scale
    Relationships between the X-ray and radio behavior of black hole X-ray binaries during outbursts have established a fundamental coupling between the accretion...

    Investigating the disc-jet coupling in accreting compact objects using the black hole candidate Swift J1753.5-0127
    In studies of accreting black holes in binary systems, empirical relations have been proposed to quantify the coupling between accretion processes and ejection...

    Irradiation of the secondary star in X-ray Nova Scorpii 1994 (=GRO J1655-40)
    We have obtained intermediate resolution optical spectra of the black-hole candidate Nova Sco 1994 in 1996 June, when the source was in an X-ray/optical active...

    Is GS:2000+25 an Eclipsing Black-Hole Binary
    We present an alternative interpretation of the quiescent optical light curve of GS2000 +25 published by Chevalier & Ilovaisky, and show that the modulation can...

    Isolating the jet in broadband spectra of XBs
    Most accretion-powered relativistic jet sources in our Galaxy are transient X-ray binaries (XBs). Efforts to coordinate multiwavelength observations of these...

    Jet spectral breaks in black hole X-ray binaries
    In X-ray binaries, compact jets are known to commonly radiate at radio to infrared frequencies, whereas at optical to γ-ray energies, the contribution of the...
