The interplay of black hole binaries with their environment in gas-rich mergers

Abstract:
I will discuss the evolution of massive black hole binaries during
the last phases of galaxy mergers. We explore the evolution of
merging black holes via high-resolution hydrodynamical simulations
designed to follow the dynamics of black holes in merger remnants,
while tracing gas accretion onto the holes with high accuracy. We
find that the mass accretion rate and the hole's dynamics and the
thermodynamical properties of the gas are strictly related. These
simulations also allow us to trace the evolution of the magnitude and
orientation of black hole spins self-consistently. I will discuss
the implications of these results for the cosmic evolution of the
massive black hole population.
