Algebraic Classification of Numerical Spacetimes and Black-Hole-Binary Remnants
Manuela Campanelli, Carlos O. Lousto, Yosef Zlochower
In this paper we develop a technique for determining the algebraic classification of a numerical spacetime, possibly resulting from a generic black-hole-binary merger, using the Ne…
Comparison of Numerical and Post-Newtonian Waveforms for Generic Precessing Black-Hole Binaries
Manuela Campanelli, Carlos O. Lousto, Hiroyuki Nakano +1
We compare waveforms and orbital dynamics from the first long-term, fully non-linear, numerical simulations of a generic black-hole binary configuration with post-Newtonian predict…
Modeling gravitational recoil from precessing highly-spinning unequal-mass black-hole binaries
Carlos O. Lousto, Yosef Zlochower
We measure the gravitational recoil for unequal-mass-black- hole-binary mergers, with the larger BH having spin a/m^H=0.8, and the smaller BH non-spinning. We choose our configurat…
Regular second order perturbations of binary black holes: The extreme mass ratio regime
Carlos O. Lousto, Hiroyuki Nakano
In order to derive the precise gravitational waveforms for extreme mass ratio inspirals (EMRI), we develop a formulation for the second order metric perturbations produced by a poi…
Extra-Large Remnant Recoil Velocities and Spins from Near-Extremal-Bowen-York-Spin Black-Hole Binaries
Sergio Dain, Carlos O. Lousto, Yosef Zlochower
We evolve equal-mass, equal-spin black-hole binaries with specific spins of a/mH 0.925, the highest spins simulated thus far and nearly the largest possible for Bowen-York black ho…
A new method to integrate (2+1)-wave equations with Dirac's delta functions as sources
Carlos O. Lousto, Hiroyuki Nakano
Unlike in the Schwarzschild black hole background, gravitational perturbations in a Kerr black hole background can not be decomposed into simple tensor harmonics in the time domain…
