Spectral Problems for Quasinormal Modes of Black Holes
Yasuyuki Hatsuda, Masashi Kimura
This is an unconventional review article on spectral problems in black hole perturbation theory. Our purpose is to explain how to apply various known techniques in quantum mechanic…

Parametrized black hole quasinormal ringdown. I. Decoupled equations for nonrotating black holes
Vitor Cardoso, Masashi Kimura, Andrea Maselli +3
Black hole solutions in general relativity are simple. The frequency spectrum of linear perturbations around these solutions (i.e., the quasinormal modes) is also simple, and there…

Perturbative quasinormal mode frequencies
Yasuyuki Hatsuda, Masashi Kimura
We often encounter a situation that black hole solutions can be regarded as continuous deformations of simpler ones, or modify general relativity by continuous parameters. We devel…
