High Energy Collisions of Black Holes Numerically Revisited
James Healy, Ian Ruchlin, Carlos O. Lousto +1
We use fully nonlinear numerical relativity techniques to study high energy head-on collision of nonspinning, equal-mass black holes to estimate the maximum gravitational radiation…
Perturbative extraction of gravitational waveforms generated with Numerical Relativity
H. Nakano, J. Healy, C. O. Lousto +1
We derive an analytical expression for extracting the gravitational waveforms at null infinity using the Weyl scalar measured at a finite radius. Our expression is based on a…
Inspiraling black-hole binary spacetimes: Challenges in transitioning from analytical to numerical techniques
Yosef Zlochower, Hiroyuki Nakano, Bruno C. Mundim +3
We explore how a recently developed analytical black-hole binary spacetime can be extended using numerical simulations to go beyond the slow-inspiral phase. The analytic spacetime…
Modeling the remnant mass, spin, and recoil from unequal-mass, precessing black-hole binaries: The Intermediate Mass Ratio Regime
Yosef Zlochower, Carlos O. Lousto
We revisit the modeling of the properties of the remnant black hole resulting the merger of a black-hole binary as a function of the parameters of the binary. We provide a set of e…
