Binary black hole mergers: Large kicks for generic spin orientations
We present results from several simulations of equal mass black holes with spin. The spin magnitudes are S=m2 0:8 in all cases, but we vary the spin orientations arbitrarily, inside and outside the orbital plane. We find that in all but one case the final merged black hole acquires a kick of more than 1000 km=s, indicating that kicks of this magnitude are likely to be generic and should be expe...
متن کاملModeling Kicks from the Merger of Generic Black-hole Binaries
Recent numerical relativistic results demonstrate that the merger of comparable-mass spinning black holes has a maximum “recoil kick” of up to ∼ 4000 km s. However the scaling of these recoil velocities with mass ratio is poorly understood. We present new runs showing that the maximum possible kick parallel to the orbital axis does not scale as ∼ η (where η is the symmetric mass ratio), as prev...
متن کاملThe Role of Primordial Kicks on Black Hole Merger Rates
Primordial stars are likely to be very massive ≥ 30 M⊙, form in isolation, and will likely leave black holes as remnants in the centers of their host dark matter halos in the mass range 10 − 10 M⊙. Such early black holes, at redshifts z∼ 10, could be the seed black holes for the many supermassive black holes found in galaxies in the local universe. If they exist, their mergers with nearby super...
متن کاملBlack Hole Kicks as New Gravitational Wave Observables.
Generic black hole binaries radiate gravitational waves anisotropically, imparting a recoil, or kick, velocity to the merger remnant. If a component of the kick along the line of sight is present, gravitational waves emitted during the final orbits and merger will be gradually Doppler shifted as the kick builds up. We develop a simple prescription to capture this effect in existing waveform mod...
متن کاملCosmological multi-black-hole solutions.
We present simple, analytic solutions to the Einstein-Maxwell equation, which describe an arbitrary number of charged black holes in a spacetime with positive cosmological constant Λ. In the limit Λ = 0, these solutions reduce to the well known Majumdar-Papapetrou (MP) solutions. Like the MP solutions, each black hole in a Λ > 0 solution has charge Q equal to its mass M , up to a possible overa...
