Multipolar analysis of spinning binaries
E. Berti, V. Cardoso, J. A. Gonzalez +2
We present a preliminary study of the multipolar structure of gravitational radiation from spinning black hole binary mergers. We consider three different spinning binary configura…
Eccentric binary black-hole mergers: The transition from inspiral to plunge in general relativity
U. Sperhake, E. Berti, V. Cardoso +3
We study the transition from inspiral to plunge in general relativity by computing gravitational waveforms of non-spinning, equal-mass black-hole binaries. We consider three sequen…
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…
