A bstract : A chain regularization method is combined with special purpose computer hardware to study the evolution of massive black hole binaries at the centers of galaxies. Preliminary results with up to N = 0.26 × 10 6 particles are presented. The decay rate of the binary is shown to decrease with increasing N , as expected on the basis of theoretical arguments. The eccentricity of the binary remains small.
