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…
Stochastic gravitational-wave background from self-interacting superradiant clouds
Yin-Da Guo, Richard Brito, Chen Yuan
Gravitational-wave (GW) observations offer a powerful probe of new fundamental fields. One well-motivated source is black hole (BH)--boson cloud systems, in which an ultralight sca…
Revisiting environmental effects on black hole quasibound-state spectra with relativistic perturbation theory
Yin-Da Guo, Qi-Xuan Xu, Richard Brito +1
We present a relativistic framework for computing corrections to the eigenfrequency spectrum of a massive scalar field in perturbed black-hole spacetimes, including first-order shi…
Extreme mass-ratio inspirals into Newtonian Proca stars
João Bernardo Silva, Richard Brito
Massive bosonic fields can form self-gravitating solitonic structures, which for vector fields are known as Proca stars. For ultralight fields, these structures can describe the co…
Resonances as signatures of scalar clouds in eccentric extreme-mass-ratio inspirals
Qi-Xuan Xu, Richard Brito, Riccardo Della Monica +2
Ultralight scalars arise naturally in many extensions to the Standard Model and are compelling dark matter candidates. Around spinning black holes, dense scalar clouds could form t…
Relativistic effects in extreme-mass-ratio inspirals within scalar clouds: Eccentric and inclined orbits
Qi-Xuan Xu, Richard Brito, Riccardo Della Monica +2
We study extreme-mass-ratio inspirals (EMRIs) evolving in a scalar cloud environment that may form through superradiant instabilities, using a fully relativistic perturbative frame…
