« Supermassive black holes from kpc to pc scales »

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.
