| 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. |
