The scalar Green function of the Kerr spacetime
Huan Yang, Fan Zhang, Aaron Zimmerman +1
In this paper we study the scalar Green function in the Kerr spacetime using WKB methods. The Green function can be expressed by Fourier-transforming to its frequency-domain counte…
Quasinormal modes of nearly extremal Kerr spacetimes: spectrum bifurcation and power-law ringdown
Huan Yang, Aaron Zimmerman, Anıl Zenginoğlu +3
We provide an in-depth investigation of quasinormal-mode oscillations of Kerr black holes with nearly extremal angular momenta. We first discuss in greater detail the two distinct…
The stability of tidally deformed neutron stars to three- and four-mode coupling
Tejaswi Venumadhav, Aaron Zimmerman, Christopher M. Hirata
It has recently been suggested that the tidal deformation of a neutron star excites daughter p- and g-modes to large amplitudes via a quasi-static instability. This would remove en…
Avenues for Analytic exploration in Axisymmetric Spacetimes. Foundations and the Triad Formalism
Jeandrew Brink, Aaron Zimmerman, Tanja Hinderer
Axially symmetric spacetimes are the only models for isolated systems with continuous symmetries that also include dynamics. For such systems, we review the reduction of the vacuum…
