    Massive Black Hole Binaries and the Low Frequency Gravitational Wave sky: Electromagnetic Signatures

    Abstract:  The inspiral and merger of massive black holes binaries (MBHBs) in galactic nuclei makes up a dominant component of the low frequency (nHZ to HZ) gravitational sky, soon detectable by the Pulsar Timing Arrays and space based interferometer LISA. Characterization of the MBHB population will shed light on the environments of galactic nuclei and also on the mutual growth of galaxies and their central black holes. This talk addresses the electromagnetic tracers that are...

     Dynamical friction and the evolution of Supermassive Black hole Binaries: the final hundred-parsec problem

    ABSTRACT: Dynamical friction is a fundamental process in astrophysics and its understanding is arguably the most important contribution of Chandrasekhar to stellar dynamics. In this talk I will discuss the results of analytical models and N-body simulations that describe the evolution of a massive black hole binary due to dynamical friction. I will show that the standard Chandrasekhar's theory leads to erroneous conclusions about the evolution of the massive...
