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…

New Generic Ringdown Frequencies at the Birth of a Kerr Black Hole
Aaron Zimmerman, Yanbei Chen
We discuss a new ringdown frequency mode for vacuum perturbations of the Kerr black hole. We evolve initial data for the vacuum radial Teukolsky equation using a near horizon appro…
