Finding quasinormal modes directly from the boundary conditions in a Schwarzschild black hole
Jeff Steinhauer
We present a conceptually simple method for finding quasinormal modes (QNMs) in a Schwarzschild black hole. QNMs are defined by their boundary conditions at infinity and at the hor…

Overdamped quasibound states inside a Schwarzschild black hole
Jeff Steinhauer, Kyriakos Destounis, Richard Brito
Schwarzschild black-hole interiors, bounded by event horizons and terminated by spacelike singularities, are regions where all physical observers are inevitably destroyed. In the g…

The ringdown-Hawking radiation connection in real and analogue black holes
Eyal Keshet, Inbar Shemesh, Jeff Steinhauer
In the usual picture of Hawking radiation, the emission is spontaneous; it is caused by nothing. In contrast, the radiation from the ringdown after a black-hole merger is caused dy…
