Binary black hole mergers: What causes the final kick? ⚫🌀⚫➡️⚫🚀

Decoding the physics of asymmetric gravitational-wave radiation and its connection to black-hole kicks.

In some binaries, the spins of the black holes are not aligned with the system’s orbital angular momentum. Merger remnants of such systems receive a recoil, also called a “kick”, with velocities of up to 5000 km/s. This happens because gravitational waves carry away linear momentum, which is conserved. Now, a team of researchers from the Max Planck Independent Research Group “Binary Merger Observations and Numerical Relativity” at the @mpi_grav has taken a closer look at the relationship between asymmetric gravitational-wave emission and kicks and found something seemingly counterintuitive…
