    The orbital period, black hole mass, and distance to the X-ray transient GRS 1716-249 ( =N Oph 93)
    We present evidence for a 0.278(8) d ( =6.7 h) orbital period in the X-ray transient GRS 1716-249 (=N Oph 93), based on a superhump modulation detected during...

    The role of massive black hole recoil in galaxy evolution
    The coalescence of a massive black hole (MBH) binary leads to the gravitational-wave recoil of the system and its ejection from the galaxy core. We have carried...
