Comparison between numerical relativity and a new class of post-Newtonian gravitational-wave phase evolutions: the non-spinning equal-mass case
Achamveedu Gopakumar, Mark Hannam, Sascha Husa +1
We compare the phase evolution of equal-mass nonspinning black-hole binaries from numerical relativity (NR) simulations with post-Newtonian (PN) results obtained from three PN appr…
Comparison between numerical-relativity and post-Newtonian waveforms from spinning binaries: the orbital hang-up case
Mark Hannam, Sascha Husa, Bernd Brügmann +1
We compare results from numerical simulations of spinning binaries in the "orbital hangup" case, where the binary completes at least nine orbits before merger, with post-Newtonian…
A template bank for gravitational waveforms from coalescing binary black holes: non-spinning binaries
P. Ajith, S. Babak, Y. Chen +15
Gravitational waveforms from the inspiral and ring-down stages of the binary black hole coalescences can be modelled accurately by approximation/perturbation techniques in general…
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…
