I’ll review the main astrophysical processes shaping the merger rate and the distributions of properties of merging massive black holes in the gravitational wave domain (LISA and PTAs), highlighting uncertainties and unknowns. Turning the question around, gravitational waves can inform us on poorly known processes in the cosmic history of massive black holes.

3. Discriminating between different scenarios for the formation and evolution of massive black holes with LISA

Different scenarios for the formation and evolution of massive black holes lead to different predictions for the population of massive black holes in the Universe. By reverse engineering the problem, we can use LISA observations to discriminate between different scenarios. However, the Universe is unlikely to be described by a single model. This can be accounted for by introducing mixing...
