Hybrid method for understanding black-hole mergers: Inspiralling case
David A. Nichols, Yanbei Chen
We adapt a method of matching post-Newtonian and black-hole-perturbation theories on a timelike surface (which proved useful for understanding head-on black-hole-binary collisions)…

Classifying the Isolated Zeros of Asymptotic Gravitational Radiation by Tendex and Vortex Lines
Aaron Zimmerman, David A. Nichols, Fan Zhang
A new method to visualize the curvature of spacetime was recently proposed. This method finds the eigenvectors of the "electric" and "magnetic" components of the Weyl tensor and, i…

Visualizing Spacetime Curvature via Frame-Drag Vortexes and Tidal Tendexes I. General Theory and Weak-Gravity Applications
David A. Nichols, Robert Owen, Fan Zhang +8
When one splits spacetime into space plus time, the Weyl curvature tensor (vacuum Riemann tensor) gets split into two spatial, symmetric, and trace-free (STF) tensors: (i) the Weyl…
