Phys. Rev. Lett. 81, 508–511 (1998)Head-On Collision of Two Unequal Mass Black HolesReceived 16 March 1998; published in the issue dated 20 July 1998 We present results from the first fully nonlinear numerical calculations of the head-on collision of two unequal mass black holes. Selected waveforms of the most dominant ℓ = 2, 3, and 4 quasinormal modes are shown, as are the total radiated energies and recoil velocities for a range of mass ratios and initial separations. Our results validate the close and distant separation limit perturbation studies, and suggest that the head-on collision scenario is not likely to produce an astrophysically significant recoil effect. © 1998 The American Physical Society URL:
