The high-energy collision of two black holes
U. Sperhake, V. Cardoso, F. Pretorius +2
We study the head-on collision of two highly boosted equal mass, nonrotating black holes. We determine the waveforms, radiated energies, and mode excitation in the center of mass f…
Exploring black hole superkicks
Bernd Bruegmann, Jose Gonzalez, Mark Hannam +2
Recent calculations of the recoil velocity in black-hole binary mergers have found kick velocities of km/s for equal-mass binaries with anti-aligned initial spins in…
Reducing eccentricity in black-hole binary evolutions with initial parameters from post-Newtonian inspiral
Sascha Husa, Mark Hannam, Jose A. Gonzalez +2
Standard choices of quasi-circular orbit parameters for black-hole binary evolutions result in eccentric inspiral. We introduce a conceptually simple method, which is to integrate…
Reducing phase error in long numerical binary black hole evolutions with sixth order finite differencing
Sascha Husa, Jose A. Gonzalez, Mark Hannam +2
We describe a modification of a fourth-order accurate ``moving puncture'' evolution code, where by replacing spatial fourth-order accurate differencing operators in the bulk of the…
Where post-Newtonian and numerical-relativity waveforms meet
Mark Hannam, Sascha Husa, Jose A. Gonzalez +2
We analyze numerical-relativity (NR) waveforms that cover nine orbits (18 gravitational-wave cycles) before merger of an equal-mass system with low eccentricity, with numerical unc…
Phenomenological template family for black-hole coalescence waveforms
P. Ajith, S. Babak, Y. Chen +15
Recent progress in numerical relativity has enabled us to model the non-perturbative merger phase of the binary black-hole coalescence problem. Based on these results, we propose a…
