Comparison of electromagnetic and gravitational radiation; what we can learn about each from the other
Richard H. Price, John W. Belcher, David A. Nichols
We compare the nature of electromagnetic fields and of gravitational fields in linearized general relativity. We carry out this comparison both mathematically and visually. In part…
Branching of quasinormal modes for nearly extremal Kerr black holes
Huan Yang, Fan Zhang, Aaron Zimmerman +3
We show that nearly extremal Kerr black holes have two distinct sets of quasinormal modes, which we call zero-damping modes (ZDMs) and damped modes (DMs). The ZDMs exist for all ha…
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…
Quasinormal-mode spectrum of Kerr black holes and its geometric interpretation
Huan Yang, David A. Nichols, Fan Zhang +3
There is a well-known, intuitive geometric correspondence between high-frequency QNMs of Schwarzschild black holes and null geodesics that reside on the light-ring : the real part…
