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…
