Black holes in galaxies: Environmental impact on gravitational-wave generation and propagation

V Cardoso, K Destounis, F Duque, RP Macedo… - Physical Review D, 2022 - APS
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. These …

Spinning black holes fall in love

A Le Tiec, M Casals - Physical Review Letters, 2021 - APS
The open question of whether a black hole can become tidally deformed by an external
gravitational field has profound implications for fundamental physics, astrophysics, and …

Tidal Love numbers of Kerr black holes

A Le Tiec, M Casals, E Franzin - Physical Review D, 2021 - APS
The open question of whether a Kerr black hole can become tidally deformed or not has
profound implications for fundamental physics and gravitational-wave astronomy. We …

Self-interacting scalar dark matter around binary black holes

JC Aurrekoetxea, J Marsden, K Clough, PG Ferreira - Physical Review D, 2024 - APS
Gravitational waves can provide crucial insights about the environments in which black
holes live. In this work, we use numerical relativity simulations to study the behavior of self …

How to assess the primordial origin of single gravitational-wave events with mass, spin, eccentricity, and deformability measurements

G Franciolini, R Cotesta, N Loutrel, E Berti, P Pani… - Physical Review D, 2022 - APS
A population of primordial black holes formed in the early Universe could contribute to at
least a fraction of the black-hole merger events detectable by current and future gravitational …

Modeling frequency-dependent tidal deformability for environmental black hole mergers

V De Luca, A Maselli, P Pani - Physical Review D, 2023 - APS
Motivated by events in which black holes can lose their environment due to tidal interactions
in a binary system, we develop a waveform model in which the tidal deformability …

Nonlinearities in the tidal Love numbers of black holes

V De Luca, J Khoury, SSC Wong - Physical Review D, 2023 - APS
Tidal Love numbers describe the linear response of a compact object under the presence of
external tidal perturbations, and they are found to vanish exactly for black holes within …

Black hole merger simulations in wave dark matter environments

J Bamber, JC Aurrekoetxea, K Clough, PG Ferreira - Physical Review D, 2023 - APS
The interaction of binary black hole mergers with their environments can be studied using
numerical relativity simulations. These start only a short finite time before merger, at which …
