- 요약Massive black holes are fundamental to our understanding of galaxy evolution and cosmology. When massive black holes inspiral and merge, general relativity predicts the emission of gravitational waves. Anisotropic gravitational wave emission causes a recoil kick to be imparted on the merger remnant. In this thesis, we present four significant consequences of gravitational wave recoil kicks, in particular focusing on the surrounding nuclear star cluster, with implications for transients and gravitational wave sources around massive black holes: 1) A new formation mechanism for eccentric nuclear disks following the merger of supermassive black holes due to the gravitational wave recoil kick, which explains the enhancement of tidal disruption events in post-merger galaxies; 2) A catalog of anisotropic star clusters surrounding recoiling supermassive black holes that lead to predictions of counter-rotating stars as well as unique density and line-of-sight velocity distributions which may be observable for nearby recoiling systems; 3) A consequence of the long-term evolution of counter-rotating eccentric stellar disks leading to increased dynamical stability, tidal disruption rates, and slow precession rates that match observations of M31; and 4) A model for the distribution of young stars in the Milky Way Galactic Center starting from a relatively small recoil kick associated with an intermediate-mass black hole merger with Sgr A* in the recent past. Many compact objects in the universe receive kicks during their formation and evolution, gravitationally affecting the orbits of surrounding material in a similar manner. The final major work included in this thesis is an application of similar kick dynamics to the context of debris disks around white dwarfs: 5) A novel dynamical mechanism for metal pollution on white dwarfs from natal kicks and the tidal disruption of planetesimals.
