Interactions of SMBH binaries with background stars in merging galaxies

As predicted by numerical relativity, the post-merger SMBH may get a kick velocity up to several thousand kilometres per hour due to the anisotropic GW radiations during the coalescence. We are interested with the co-evolution between the recoiling SMBH and the host galaxy. By using one million particle direct N-body simulations on special many-core hardware (GPU cluster), we can study the evolution of tidal disruption rates from the galaxy merging stage to the end of recoil phase.
