"A B S T R AC T\r\nIn this work, I investigate the dynamical evolution of supermassive black hole (SMBH) binaries\r\nand triples using high-resolution N -body simulations. Starting from cosmological initial condi-\r\ntions, I characterize the effects of stellar dynamics on the formation and evolution of SMBH\r\nbinaries. I perform numerical tests and benchmarks of the novel N -body code φ-GRAPE-hybrid\r\nand discuss how numerical parameters affect the evolution of SMBH binaries. I then simulate\r\na hard SMBH binary system embedded in a triaxial and gas-poor galaxy merger remnant. I\r\ninvestigate the properties of loss cone stars that interact strongly with the SMBH binary and\r\nfind that the summed energy changes of these stars match very well with the overall binary\r\nenergy change, demonstrating that stellar interactions are the primary drivers of SMBH binary\r\nhardening in triaxial, gas-poor systems. I also investigate the orbital and phase-space properties\r\nof these stars and distinguish three different populations based on their apocenter. Then, I\r\ninvestigate the population of SMBH triple systems in the IllustrisTNG100-1 cosmological\r\nsimulation. Using the tree code bonsai2 , I perform zoom simulations of six of these triple\r\nSMBH candidates. I then present the orbital evolution of the black holes following the mergers\r\nof their host galaxies and examine prospects for their coalescence."^^ . "2021" . . . . . . . "Branislav"^^ .
