Abstract: BRIDGE is a tree and direct hybrid N-body method developed to treat dense regions embedded in larger scale systems, such as star clusters and/or black holes (BHs) in galaxies. Using BRIDGE, we performed N-body simulations of merging star clusters and the merger of galaxies including nuclear star clusters (NCs) and BHs. In our model, the BH binary can merge in timescale of a few hundred Myr after the merger of the galaxies, assuming the gravitational wave emission. The NCs are completely disrupted during the merger and the central density of the galaxy is depleted at the moment when the BH binary coalesces.
