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…
Plasma-wave generation in a dynamic spacetime
Huan Yang, Fan Zhang
We propose a new electromagnetic-emission mechanism in magnetized, force-free plasma, which is driven by the evolution of the underlying dynamic spacetime. In particular, the emiss…
Magnetosphere of a Kerr black hole immersed in magnetized plasma and its perturbative mode structure
Huan Yang, Fan Zhang, Luis Lehner
This work studies jet-like electromagnetic configurations surrounding a slowly-spinning black-hole immersed in a uniformly magnetized force-free plasma. In the first part of this w…
Coupled Oscillator Model for Nonlinear Gravitational Perturbations
Huan Yang, Fan Zhang, Stephen R. Green +1
Motivated by the gravity/fluid correspondence, we introduce a new method for characterizing nonlinear gravitational interactions. Namely we map the nonlinear perturbative form of t…
Stability of exact force-free electrodynamic solutions and scattering from spacetime curvature
Fan Zhang, Sean T. McWilliams, Harald P. Pfeiffer
Recently, a family of exact force-free electrodynamic (FFE) solutions was given by Brennan, Gralla and Jacobson, which generalizes earlier solutions by Michel, Menon and Dermer, an…
