Reply to "On the branching of quasinormal resonances of near-extremal Kerr black holes" by Shahar Hod
Aaron Zimmerman, Huan Yang, Fan Zhang +3
In a study of the quasinormal mode frequencies of nearly extremal black holes, we pointed out a bifurcation of the mode spectrum into modes with finite decay and modes with vanishi…
The Quasinormal Modes of Weakly Charged Kerr-Newman Spacetimes
Zachary Mark, Huan Yang, Aaron Zimmerman +1
The resonant mode spectrum of the Kerr-Newman spacetime is presently unknown. These modes, called the quasinormal modes, play a central role in determining the stability of Kerr-Ne…
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…
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…
Gravitational-wave signatures of the absence of an event horizon. II. Extreme mass ratio inspirals in the spacetime of a thin-shell gravastar
Paolo Pani, Emanuele Berti, Vitor Cardoso +2
We study gravitational-wave emission from the quasi-circular, extreme mass ratio inspiral of compact objects of mass m0 into massive objects of mass M>>m0 whose external metric is…
Momentum flow in black-hole binaries: II. Numerical simulations of equal-mass, head-on mergers with antiparallel spins
Geoffrey Lovelace, Yanbei Chen, Michael Cohen +6
Research on extracting science from binary-black-hole (BBH) simulations has often adopted a "scattering matrix" perspective: given the binary's initial parameters, what are the fin…
