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…
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…
One-Loop Tensor Power Spectrum from a Non-Canonical Spectator Field during Inflation
Zhe Li, Chen Yuan, Qing-Guo Huang
We compute the full one-loop corrections to the primordial tensor power spectrum in an inflationary scenario with a {non-canonical spectator field}, using the in-in formalism. We d…
