The quasinormal modes of Kerr-Newman black holes: a separated approach
Kyriakos Destounis, Vitor Cardoso, Peter Hintz
We compute Kerr-Newman quasinormal modes using a recently found exact separation of the gravitoelectric perturbation equations. For each spin-label , a matrix angular ordin…
Chaotic signatures in extreme-mass-ratio systems surrounded by bosonic environments
Qi-Xuan Xu, Kyriakos Destounis, Yin-Da Guo +2
Extreme-mass-ratio inspirals are key gravitational-wave sources for testing strong gravity and the environments of massive black holes. While orbital motion in Kerr black hole spac…
Tidally-enhanced resonances in extreme-mass-ratio inspirals: A tertiary path to chaos
Kyriakos Destounis, Takuya Katagiri, Sajal Mukherjee +1
Extreme-mass-ratio inspirals (EMRIs) provide a unique laboratory for probing strong-field gravity and complex relativistic dynamics. We study a tidally deformed EMRI composed of a…
