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…
On energy extraction from Q-balls and other fundamental solitons
Vitor Cardoso, Rodrigo Vicente, Zhen Zhong
Energy exchange mechanisms have important applications in particle physics, gravity, fluid mechanics, and practically every field in physics. In this letter we show, both in freque…
Relativistic drag forces on black holes from scalar dark matter clouds of all sizes
Dina Traykova, Rodrigo Vicente, Katy Clough +4
We use numerical simulations of scalar field dark matter evolving on a moving black hole background to confirm the regime of validity of (semi-)analytic expressions derived from fi…
Can gravitational-wave memory help constrain binary black-hole parameters? A LISA case study
Silvia Gasparotto, Rodrigo Vicente, Diego Blas +2
Besides the transient effect, the passage of a gravitational wave also causes a persistent displacement in the relative position of an interferometer's test masses through the \emp…
Parasitic black holes: the swallowing of a fuzzy dark matter soliton
Vitor Cardoso, Taishi Ikeda, Rodrigo Vicente +1
Fuzzy dark matter is an exciting alternative to the standard cold dark matter paradigm, reproducing its large scale predictions, while solving most of the existing tension with sma…
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…
Dynamical friction of black holes in ultralight dark matter
Rodrigo Vicente, Vitor Cardoso
In this work we derive simple closed-form expressions for the dynamical friction acting on black holes moving through ultralight (scalar field) dark matter, covering both non-relat…
The Gravity of Classical Fields: And Its Effect on the Dynamics of Gravitational Systems
Rodrigo Vicente
Classical fields are ubiquitous in theoretical physics. They find applications in almost all areas of physics, from condensed matter and particle physics to cosmology and astrophys…
Eccentricity evolution of compact binaries and applications to gravitational-wave physics
Vitor Cardoso, Caio F. B. Macedo, Rodrigo Vicente
Searches for gravitational waves from compact binaries focus mostly on quasi-circular motion, with the rationale that wave emission circularizes the orbit. Here, we study the gener…
The response of ultralight dark matter to supermassive black holes and binaries
Lorenzo Annulli, Vitor Cardoso, Rodrigo Vicente
Scalar fields can give rise to confined structures, such as boson stars or Q-balls. These objects are interesting hypothetical new "dark matter stars," but also good descriptions o…
A semi-linear wave model for critical collapse
Isabel Suárez Fernández, Rodrigo Vicente, David Hilditch
In spherical symmetry compelling numerical evidence suggests that in general relativity solutions near the threshold of black hole formation exhibit critical behavior. One aspect o…
Stirred and shaken: dynamical behavior of boson stars and dark matter cores
Lorenzo Annulli, Vitor Cardoso, Rodrigo Vicente
Bosonic fields can give rise to self-gravitating structures. These are interesting hypothetical new "dark matter stars" and good descriptions of dark matter haloes if the fields ar…
Prospects for Fundamental Physics with LISA
Enrico Barausse, Emanuele Berti, Thomas Hertog +318
In this paper, which is of programmatic rather than quantitative nature, we aim to further delineate and sharpen the future potential of the LISA mission in the area of fundamental…
Test fields cannot destroy extremal de Sitter black holes
Jose Natario, Rodrigo Vicente
We determine the timelike Killing vector field that gives the correct definition of energy for test fields propagating in a Kerr-Newman-de Sitter spacetime, and use this result to…
Moving black holes: energy extraction, absorption cross-section and the ring of fire
Vitor Cardoso, Rodrigo Vicente
We consider the interaction between a plane wave and a (counter-moving) black hole. We show that energy is transferred from the black hole to the wave, giving rise to a negative ab…
Dynamical friction in slab geometries and accretion disks
Rodrigo Vicente, Vitor Cardoso, Miguel Zilhão
The evolution of planets, stars and even galaxies is driven, to a large extent, by dynamical friction of gravitational origin. There is now a good understanding of the friction pro…
Black holes, gravitational waves and fundamental physics: a roadmap
Leor Barack, Vitor Cardoso, Samaya Nissanke +203
The grand challenges of contemporary fundamental physics---dark matter, dark energy, vacuum energy, inflation and early universe cosmology, singularities and the hierarchy problem-…
The Penrose process, superradiance and ergoregion instabilities
Rodrigo Vicente, Vitor Cardoso, Jorge C. Lopes
Superradiant scattering is a radiation enhancement process that takes place in many contexts, and which has recently found exciting applications in astro and particle physics. In t…
Rotating elastic string loops in flat and black hole spacetimes: stability, cosmic censorship and the Penrose process
Jose Natario, Leonel Queimada, Rodrigo Vicente
We rederive the equations of motion for relativistic strings, that is, one-dimensional elastic bodies whose internal energy depends only on their stretching, and use them to study…
Test fields cannot destroy extremal black holes
Jose Natario, Leonel Queimada, Rodrigo Vicente
We prove that (possibly charged) test fields satisfying the null energy condition at the event horizon cannot overspin/overcharge extremal Kerr-Newman or Kerr-Newman-anti de Sitter…
