Post-adiabatic waveforms from extreme mass ratio inspirals in the presence of dark matter
Mostafizur Rahman, Takuya Takahashi
Extreme mass-ratio inspirals (EMRIs), in which a solar mass compact object is whirling around a supermassive black hole, act as precise tracers of the spacetime geometry and astrop…

Resonance of black hole quasinormal modes in coupled systems
Takuya Takahashi, Hayato Motohashi, Kazufumi Takahashi
Black hole quasinormal modes (QNMs) can exhibit resonant excitations associated with avoided crossings in their complex frequency spectrum. Such resonance phenomena can serve as no…
