    Events leading up to the 2015 June Outburst of V404 Cyg
    On 2015 June 15 the burst alert telescope (BAT) on board Swift detected an X-ray outburst from the black hole (BH) transient V404 Cyg. We monitored V404 Cyg for...

    Evidence for a compact jet dominating the broad-band spectrum of the black hole accretor XTE J1550-564
    The black hole X-ray binary XTE J1550-564 was monitored extensively at X-ray, optical and infrared wavelengths throughout its outburst in 2000. We show that it...

    Evidence for an Outer Disk in the Prototype ``Compact Elliptical'' Galaxy M32
    M32 is the prototype for the relatively rare class of galaxies referred to as compact ellipticals. It has been suggested that M32 may be a tidally disturbed r1...

    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...

    Extremely fast orbital decay of the black hole X-ray binary Nova Muscae 1991
    We present new medium-resolution spectroscopic observations of the black hole X-ray binary Nova Muscae 1991 taken with X-Shooter spectrograph installed at the 8...

    Failed-transition outbursts in black hole low-mass X-ray binaries
    Black hole low-mass X-ray binaries (BH LMXBs) evolve in a similar way during outburst. Based on the X-ray spectrum and variability, this evolution can be...

    Fast infrared variability from a relativistic jet in GX 339-4
    We present the discovery of fast infrared/X-ray correlated variability in the black hole transient GX 339-4. The source was observed with subsecond time...

    Fast orbital decays of black hole X-ray binaries: XTE J1118+480 and A0620-00★
    We present new 10.4 m-GTC/OSIRIS spectroscopic observations of the black hole X-ray binary XTE J1118+480 that confirm the orbital period decay at dot{P}=-1.90±...

    Fifteen years of XMM-Newton and Chandra monitoring of Sgr A★: evidence for a recent increase in the bright flaring rate
    We present a study of the X-ray flaring activity of Sgr A⋆ during all the 150 XMM-Newton and Chandra observations pointed at the Milky Way centre over the last...
