Long-term evolution of massive black hole binaries. II. Binary evolution in low-density galaxies
We use direct-summation N -body integrations to follow the evolution of binary black holes at the centers of galaxy models with large, constant-density cores. Particle numbers as large as 0.4 × 10 are considered. The results are compared with the predictions of loss-cone theory, under the assumption that the supply of stars to the binary is limited by the rate at which they can be scattered int...
متن کاملMassive 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 کاملEvolution of Massive Black Hole Binaries
We present the results of large-scale N -body simulations of the stellar-dynamical evolution of massive black hole binaries at the center of spherical galaxies. We focus on the dependence of the hardening rate on the relaxation timescale of the parent galaxy. A simple theoretical argument predicts that a binary black hole creates a “loss cone” around it. Once the stars in the loss cone are depl...
متن کاملLong-term Evolution of Massive Black Hole Binaries. Iii. Binary Evolution in Collisional Nuclei
In galactic nuclei with sufficiently short relaxation times, binary supermassive black holes can evolve beyond their stalling radii via continued interaction with stars. We study this “collisional” evolutionary regime using both fully self-consistent N-body integrations and approximate Fokker-Planck models. The N-body integrations employ particle numbers up to 0.26× 106 and a direct-summation p...
متن کاملLong Term Evolution of Massive Black Hole Binaries
The long-term evolution of massive black hole binaries at the centers of galaxies is studied in a variety of physical regimes, with the aim of resolving the “final parsec problem,” i.e. how black hole binaries manage to shrink to separations at which emission of gravity waves becomes efficient. A binary ejects stars by the gravitational slingshot and carves out a loss cone in the host galaxy. C...
