Massive Black Hole Binary Evolution
Coalescence of binary supermassive black holes (SBHs) would constitute the strongest sources of gravitational waves to be observed by LISA. While the formation of binary SBHs during galaxy mergers is almost inevitable, coalescence requires that the separation between binary components first drop by a few orders of magnitude, due presumably to interactions of the binary with stars and gas in a g...
متن کاملBinary Dynamics near a Massive Black Hole
We analyze the dynamical evolution of binary stars that interact with a static background of single stars in the environment of a massive black hole (MBH). All stars are considered to be single mass, Newtonian point particles. We follow the evolution of the energy E and angular momentum J of the center of mass of the binaries with respect to the MBH, as well as their internal semi-major axis a,...
متن کاملA new mechanism for massive binary black hole coalescences
Massive binary black holes (BBHs) are inevitably formed in the merged galactic nuclei before the black holes finally merge by emitting the gravitational radiation. However, it is still unknown how a massive BBH evolves after its semi-major axis reached to the sub-parsec/parsec scale where the dynamical friction with the neighboring stars is ineffective (the so-called the final parsec problem). ...

متن کاملMerging of a massive black hole binary II
In this paper, the second in a series of two, we justify two important assumptions on which the result is based that in course of a galaxy merger the slingshot ejection of bound stars is sufficiently efficient to allow a supermassive black hole binary to merge. A steep cusp with a power law index of 2.5–3 is required which is as massive as the binary and surrounds the BHs when the binary become...
