Forced motion near black holes
Jonathan R. Gair, Eanna E. Flanagan, Steve Drasco +2
We present two methods for integrating forced geodesic equations in the Kerr spacetime, which can accommodate arbitrary forces. As a test case, we compute inspirals under a simple…
Frame-Dragging Vortexes and Tidal Tendexes Attached to Colliding Black Holes: Visualizing the Curvature of Spacetime
Robert Owen, Jeandrew Brink, Yanbei Chen +8
When one splits spacetime into space plus time, the spacetime curvature (Weyl tensor) gets split into an "electric" part E_{jk} that describes tidal gravity and a "magnetic" part B…
Reducing orbital eccentricity of precessing black-hole binaries
Alessandra Buonanno, Lawrence E. Kidder, Abdul H. Mroué +2
Building initial conditions for generic binary black-hole evolutions without initial spurious eccentricity remains a challenge for numerical-relativity simulations. This problem ca…
Simulating merging binary black holes with nearly extremal spins
Geoffrey Lovelace, Mark A. Scheel, Bela Szilagyi
Astrophysically realistic black holes may have spins that are nearly extremal (i.e., close to 1 in dimensionless units). Numerical simulations of binary black holes are important t…
Transient resonances in the inspirals of point particles into black holes
Eanna E. Flanagan, Tanja Hinderer
We show that transient resonances occur in the two body problem in general relativity, in the highly relativistic, extreme mass-ratio regime for spinning black holes. These resonan…
First-post-Newtonian quadrupole tidal interactions in binary systems
Justin Vines, Éanna É. Flanagan
We consider tidal coupling in a binary stellar system to first-post-Newtonian order. We derive the orbital equations of motion for bodies with spins and mass quadrupole moments and…
Gravitational Interactions in a General Multibrane Model
Jolyon K. Bloomfield, Éanna É. Flanagan
The gravitational interactions of the four-dimensional effective theory describing a general -brane model in five dimensions without radion stabilization are analyzed. Both unco…
Spectral methods for the wave equation in second-order form
Nicholas W. Taylor, Lawrence E. Kidder, Saul A. Teukolsky
Current spectral simulations of Einstein's equations require writing the equations in first-order form, potentially introducing instabilities and inefficiencies. We present a new p…
Measuring orbital eccentricity and periastron advance in quasi-circular black hole simulations
Abdul H. Mroué, Harald P. Pfeiffer, Lawrence E. Kidder +1
We compare different methods of computing the orbital eccentricity of quasi-circular binary black hole systems using the orbital variables and gravitational wave phase and frequenc…
Degeneracy measures for the algebraic classification of numerical spacetimes
Robert Owen
We study the issue of algebraic classification of the Weyl curvature tensor, with a particular focus on numerical relativity simulations. The spacetimes of interest in this context…
Hyperboloidal evolution of test fields in three spatial dimensions
Anil Zenginoglu, Lawrence E. Kidder
We present the numerical implementation of a clean solution to the outer boundary and radiation extraction problems within the 3+1 formalism for hyperbolic partial differential equ…
A four-dimensional description of five-dimensional N-brane models
Jolyon K. Bloomfield, Éanna É. Flanagan
We propose a new method for obtaining the four-dimensional effective gravitational theory for five-dimensional braneworld models with arbitrary numbers of branes in a low energy re…
Effective-one-body waveforms calibrated to numerical relativity simulations: coalescence of non-precessing, spinning, equal-mass black holes
Yi Pan, Alessandra Buonanno, Luisa T. Buchman +4
We present the first attempt at calibrating the effective-one-body (EOB) model to accurate numerical-relativity simulations of spinning, non-precessing black-hole binaries. Alignin…
