Supermassive black holes (BHs) reside in the center of most mas-
sive galaxies and are thought to play a crucial role in the big picture of galaxy evolution. Since galaxies merge, we expect BHs to get closer and form binaries, an inevitable step before their merger and the emission of gravitational waves that we might ob- serve with LISA. We focus on the formation of the binary and show, using ideal simulations of galaxy mergers, that this process is far to be captured in cosmological simulations. This prevents from predicting self-consistently the merger rate of supermassive BHs using cosmological simulations. We present a new model which will overcomes this issue. |
