| « Massive black holes mergers and gravitational wave recoil in a cosmological context » |
|

| When two massive black holes (MBHs) merge, gravitational waves are typically radiated anisotropically, carrying away linear momentum. The remnant MBH receives a recoil kick in the opposite direction, which can reach a velocity of up to ~5000 km/s. The MBH might subsequently be displaced from the nucleus of the galaxy or even escape it completely. This can have profound implications for the evolution of MBHs and their host galaxies. Moreover, the magnitude of the recoil kick depends on the spins, spin orientations, masses, and orbital angular momentum of the merging MBHs. These quantities are linked to the cosmic history of the MBHs. In this talk, we will discuss the role of recoil kicks in a cosmological context. |
