Black Hole Spin Axis in Numerical Relativity
Robert Owen, Alex S. Fox, John A. Freiberg +1
Colliding black holes are systems of profound interest in both gravitational wave astronomy and in gravitation theory, and a variety of methods have been developed for modeling the…
Nearly extremal apparent horizons in simulations of merging black holes
Geoffrey Lovelace, Mark A. Scheel, Robert Owen +9
The spin angular momentum of an isolated Kerr black hole is bounded by the surface area of its apparent horizon: , with equality for extremal black holes. In thi…
A catalog of 174 binary black-hole simulations for gravitational-wave astronomy
Abdul H. Mroue, Mark A. Scheel, Bela Szilagyi +14
This paper presents a publicly available catalog of 174 numerical binary black-hole simulations following up to 35 orbits. The catalog includes 91 precessing binaries, mass ratios…
Visualizing Spacetime Curvature via Frame-Drag Vortexes and Tidal Tendexes III. Quasinormal Pulsations of Schwarzschild and Kerr Black Holes
David A. Nichols, Aaron Zimmerman, Yanbei Chen +5
In recent papers, we and colleagues have introduced a way to visualize the full vacuum Riemann curvature tensor using frame-drag vortex lines and their vorticities, and tidal tende…
Visualizing Spacetime Curvature via Frame-Drag Vortexes and Tidal Tendexes II. Stationary Black Holes
Fan Zhang, Aaron Zimmerman, David A. Nichols +5
When one splits spacetime into space plus time, the Weyl curvature tensor (which equals the Riemann tensor in vacuum) splits into two spatial, symmetric, traceless tensors: the tid…
A geometric approach to the precession of compact binaries
Michael Boyle, Robert Owen, Harald P. Pfeiffer
We discuss a geometrical method to define a preferred reference frame for precessing binary systems and the gravitational waves they emit. This minimal-rotation frame is aligned wi…
