Abstract
For being able to simulate ‘collisional’ systems, i.e. systems like globular star clusters where particle orbits are dominated
by two-body encounters, it is necessary to use precise N-body algorithms. Furthermore, Black Hole Mergers can have a
significant effect on the evolution of such systems. Therefore, the publicly available code NBody6++GPU was used to
simulate the evolution of dense clusters of only Black Holes and the simulations were then used to analyse Black Hole
Merger and Binary parameters. Finally, to improve the code, Numerical Relativity fitting formulae for Recoil Kicks of
Black Hole Mergers were implemented and its effects investigated. It was determined that the distributions of remnant
spins and merger kick velocities are clearly dependent on initial spin alignments.
