Massive Black Hole Binaries: Dynamical Evolution and Observational Signatures
Figure 2
Two consecutive stages of the MBHB decay in the nucleus of a gas-rich galaxy merger remnant. (a) Central region (~5 pc) of a large-scale (100 pc) massive () circumnuclear disk, embedding a sub-pc MBHB (from one of the simulations in [56]). The color code refers to the gas density (high densities in yellow). (b) an eccentric MBHB embedded in a sub-pc circumbinary disk (from [62]). Here, darker blue refers to higher densities.
