    Revealing the Nature of the ULX and X-Ray Population of the Spiral Galaxy NGC 4088
    We present the first Chandra and Swift X-ray study of the spiral galaxy NGC 4088 and its ultraluminous X-ray source (ULX N4088-X1). We also report very long...

    Soft X-ray emission lines in the X-ray binary Swift J1858.6-0814 observed with XMM-Newton Reflection Grating Spectrometer: disc atmosphere or wind?
    We find soft X-ray emission lines from the X-ray binary Swift J1858.6-0814 in data from XMM-NewtonReflection Grating Spectrometer (RGS): N VII, O VII, and O...

    Spectral and timing evolution of the bright failed outburst of the transient black hole Swift J174510.8-262411
    We studied time variability and spectral evolution of the Galactic black hole transient Swift J174510.8-262411 during the first phase of its outburst. INTEGRAL...

    Spectral state transitions of the Ultraluminous X-ray Source IC 342 X-1
    We observed the Ultraluminous X-ray Source (ULX) IC 342 X-1 simultaneously in X-ray and radio with Chandra and the JVLA to investigate previously reported...

    Starbursts and black hole masses in X-shaped radio galaxies: Signatures of a merger event?
    We present new spectroscopic identifications of 12 X-shaped radio galaxies and use the spectral data to derive starburst histories and masses of the nuclear...

    Supermassive black holes from OASIS and SAURON integral-field kinematics
    Supermassive black holes are a key element in our understanding of how galaxies form. Most of the progress in this very active field of research is based on...
