Uncovering subdominant multipole asymmetries in binary black-hole mergers
Jannik Mielke, Angela Borchers, Frank Ohme
In dynamically formed binaries, the spins of the black holes tend to be misaligned with the system's orbital angular momentum. This causes the spins to precess and leads to an asym…

Revisiting the relationship of black-hole kicks and multipole asymmetries
Jannik Mielke, Shrobana Ghosh, Angela Borchers +1
Precession in black-hole binaries is caused by a misalignment between the total spin and the orbital angular momentum. The gravitational-wave emission of such systems is anisotropi…

Observability of spin precession in the presence of a black-hole remnant kick
Angela Borchers, Frank Ohme, Jannik Mielke +1
Remnants of binary black-hole mergers can gain significant recoil or kick velocities when the binaries are asymmetric. The kick is the consequence of anisotropic emission of gravit…
