    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...

    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...
