A recipe for echoes from exotic compact objects
Zachary Mark, Aaron Zimmerman, Song Ming Du +1
Gravitational wave astronomy provides an unprecedented opportunity to test the nature of black holes and search for exotic, compact alternatives. Recent studies have shown that exo…
Damped and zero-damped quasinormal modes of charged, nearly extremal black holes
Aaron Zimmerman, Zachary Mark
Despite recent progress, the complete understanding of the perturbations of charged, rotating black holes as described by the Kerr-Newman metric remains an open and fundamental pro…
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…
Quasinormal Modes Beyond Kerr
Aaron Zimmerman, Huan Yang, Zachary Mark +2
The quasinormal modes (QNMs) of a black hole spacetime are the free, decaying oscillations of the spacetime, and are well understood in the case of Kerr black holes. We discuss a m…
