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…
Excitation of scalar quasi-normal modes from boson clouds
Enrico Cannizzaro, Marco Palleschi, Laura Sberna +2
Massive scalar fields on black hole backgrounds generally admit two families of modes: quasi-bound states (QBS) and quasinormal modes (QNM). We demonstrate the orthogonality betwee…
Constraining the Swift Memory Burden Effect with GW250114-like Events
Chen Yuan, Richard Brito
Black hole spectroscopy allows to infer the properties of the remnant of a binary black hole coalescence. Motivated by the recent proposal that a black hole's information load can…
Overdamped quasibound states inside a Schwarzschild black hole
Jeff Steinhauer, Kyriakos Destounis, Richard Brito
Schwarzschild black-hole interiors, bounded by event horizons and terminated by spacelike singularities, are regions where all physical observers are inevitably destroyed. In the g…
Extreme mass ratio inspirals around topological stars
Marco Melis, Richard Brito, Paolo Pani
We study a point scalar charge in circular orbit around a topological star, a regular, horizonless soliton emerging from dimensional compactification of Einstein-Maxwell theory in…
Detectability of gravitational atoms in black hole binaries with the Einstein Telescope
Riccardo Della Monica, Richard Brito
Rotating black holes can amplify ultralight bosonic fields through superradiance, forming macroscopic clouds known as gravitational atoms. When the cloud forms around one of the co…
The Science of the Einstein Telescope
Adrian Abac, Raul Abramo, Simone Albanesi +485
Einstein Telescope (ET) is the European project for a gravitational-wave (GW) observatory of third-generation. In this paper we present a comprehensive discussion of its science ob…
Environmental effects in extreme mass ratio inspirals: perturbations to the environment in Kerr
Conor Dyson, Thomas F. M. Spieksma, Richard Brito +2
Future gravitational wave observatories open a unique avenue to study the environments surrounding black holes. Intermediate or extreme mass ratio inspirals will spend thousands to…
Impact of relativistic waveforms in LISA's science objectives with extreme-mass-ratio inspirals
Hassan Khalvati, Alessandro Santini, Francisco Duque +4
Extreme-Mass-Ratio Inspirals (EMRIs) are one of the key targets for future space-based gravitational wave detectors, such as LISA. The scientific potential of these sources can onl…
