Extreme mass-ratio inspirals in ultra-light dark matter
Francisco Duque, Caio F. B. Macedo, Rodrigo Vicente +1
Previous works have argued that future gravitational-wave detectors will be able to probe the properties of astrophysical environments where binary coalesce, including accretion di…
Gravitational Waves and the Galactic Potential
Francisco Duque
Over the next decade, third-generation interferometers and the space-based LISA mission will observe binaries in galactic centers involving supermassive black holes with millions o…
Black-hole spectroscopy: quasinormal modes, ringdown stability and the pseudospectrum
Kyriakos Destounis, Francisco Duque
Black-hole spectroscopy is a powerful tool to probe the Kerr nature of astrophysical compact objects and their environment. The observation of multiple ringdown modes in gravitatio…
Constraints on massive gravity from dipolar mode excitations
Vitor Cardoso, Francisco Duque, Andrea Maselli +1
We study extreme-mass-ratio systems in theories admitting the Schwarzschild solution and propagating a massive graviton. We show that, in addition to small corrections to the quadr…
Agnostic black hole spectroscopy: Quasinormal mode content of numerical relativity waveforms and limits of validity of linear perturbation theory
Vishal Baibhav, Mark Ho-Yeuk Cheung, Emanuele Berti +5
Black hole spectroscopy is the program to measure the complex gravitational-wave frequencies of merger remnants, and to quantify their agreement with the characteristic frequencies…
Gravitational waves from extreme-mass-ratio systems in astrophysical environments
Vitor Cardoso, Kyriakos Destounis, Francisco Duque +2
We establish a generic, fully-relativistic formalism to study gravitational-wave emission by extreme-mass-ratio systems in spherically-symmetric, non-vacuum black-hole spacetimes.…
Nonlinear effects in black hole ringdown
Mark Ho-Yeuk Cheung, Vishal Baibhav, Emanuele Berti +8
We report evidence for nonlinear modes in the ringdown stage of the gravitational waveform produced by the merger of two comparable-mass black holes. We consider both the coalescen…
New Horizons for Fundamental Physics with LISA
K. G. Arun, Enis Belgacem, Robert Benkel +138
The Laser Interferometer Space Antenna (LISA) has the potential to reveal wonders about the fundamental theory of nature at play in the extreme gravity regime, where the gravitatio…
Stability of the fundamental quasinormal mode in time-domain observations against small perturbations
Emanuele Berti, Vitor Cardoso, Mark Ho-Yeuk Cheung +4
Black hole spectroscopy with gravitational waves is an important tool to measure the mass and spin of astrophysical black holes and to test their Kerr nature. Next-generation groun…
Resonances, black hole mimickers and the greenhouse effect: consequences for gravitational-wave physics
Vitor Cardoso, Francisco Duque
Ultracompact objects with photonspheres are known to mimic many observational features of black holes. It has been suggested that anomalous tidal heating or the presence of resonan…
Black holes in galaxies: environmental impact on gravitational-wave generation and propagation
Vitor Cardoso, Kyriakos Destounis, Francisco Duque +2
We introduce a family of solutions of Einstein's gravity minimally coupled to an anisotropic fluid, describing asymptotically flat black holes with "hair" and a regular horizon. Th…
The light ring and the appearance of matter accreted by black holes
Vitor Cardoso, Francisco Duque, Arianna Foschi
The geometry of black hole spacetimes can be probed with exquisite precision in the gravitational-wave window, and possibly also in the optical regime. We study the accretion of br…
Gravitational tuning forks and hierarchical triple systems
Vitor Cardoso, Francisco Duque, Gaurav Khanna
We study gravitational wave (GW) emission in the strong-field regime by a hierarchical triple system composed of a binary system placed in the vicinity of a supermassive black hole…
Tidal effects and disruption in superradiant clouds: a numerical investigation
Vitor Cardoso, Francisco Duque, Taishi Ikeda
The existence of light, fundamental bosonic fields is an attractive possibility that can be tested via black hole observations. We study the effect of a tidal field -- caused by a…
Environmental effects in GW physics: tidal deformability of black holes immersed in matter
Vitor Cardoso, Francisco Duque
The tidal deformability of compact objects by a companion has a detectable imprint in the gravitational waves emitted by a binary system. This effect is governed by the so-called t…
Motion in time-periodic backgrounds with applications to ultralight dark matter haloes at galactic centers
Mateja Bošković, Francisco Duque, Miguel C. Ferreira +2
We consider motion in spherically symmetric but time-dependent backgrounds. This problem is of interest, for example, in the context of ultralight dark matter, where galactic haloe…
