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…
Inspirals into bosonic dark matter stars and chirp mimickers
Caio F. B. Macedo, Haroldo C. D. Lima, Raissa F. P. Mendes +2
We investigate extreme--mass--ratio inspirals in which a stellar-mass compact object orbits a supermassive bosonic dark matter star, modeled as a boson star, using fully relativist…
Dark matter mounds from the collapse of supermassive stars: a general-relativistic analysis
Roberto Caiozzo, Gianfranco Bertone, Piero Ullio +3
Recent work has highlighted the importance of a fully relativistic treatment of the dephasing of gravitational waves induced by dark-matter overdensities in extreme mass-ratio insp…
Extreme-mass-ratio inspirals in relativistic accretion discs
Francisco Duque, Laura Sberna, Andrew Spiers +1
We compute relativistic Lindblad torques for circular, equatorial extreme-mass-ratio inspirals (EMRIs) embedded in relativistic thin accretion discs, including spinning black hole…
Mass and spin coevolution of black holes inspiralling through dark matter
Theophanes K. Karydas, Rodrigo Vicente, Gianfranco Bertone
In extreme/intermediate-mass-ratio inspirals (E/IMRIs) embedded in dark-matter (DM) spikes, the secondary black hole can accrete collisionless particles from the surrounding halo.…
Fully Relativistic Treatment of Extreme Mass-Ratio Inspirals in Collisionless Environments
Rodrigo Vicente, Theophanes K. Karydas, Gianfranco Bertone
Future mHz gravitational wave (GW) interferometers will precisely probe massive black hole environments, such as accretion discs, cold dark matter overdensities, and clouds of ultr…
