Web摘要：. Since many or most galaxies have central massive black holes (BHs), mergers of galaxies can form massive binary black holes (BBHs). The evolution of BBHs depends on BH mass ratio and host galaxy type. BBHs with very low mass ratios (say, 0.001) are hardly ever formed by mergers of galaxies because the dynamical friction timescale is ...
