On the survival of dark matter spikes: Stellar and compact-object perturbations
Theophanes K. Karydas, Francesca Scarcella, Bradley J. Kavanagh +1
Establishing realistic expectations for the dark matter (DM) distribution near a supermassive black hole (BH) is essential for assessing environmental imprints on gravitational wav…
Multi-messenger and time-domain astronomy in the 2040s
Samaya Nissanke, Nikhil Sarin, Chris Copperwheat +31
Multi-messenger astronomy will be transformed in the 2040s by an unprecedented volume of detections from next-generation gravitational wave, high-energy, and ultra-high energy neut…
Measuring the neutron star equation of state from EMRIs in dark matter environments with LISA
Theophanes K. Karydas, Gianfranco Bertone
Gravitational-wave observations of extreme mass-ratio inspirals (EMRIs) in vacuum are largely insensitive to the internal structure of the small compact companion. We show that thi…
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.…
GW emission and relativistic dynamical friction in intermediate mass ratio inspirals
P. Di Cintio, G. Bertone, C. Chiari +4
We present a set of preliminary simulations of intermediate mass ratio inspirals (IMRIs) inside dark matter (DM) spikes accounting for post-Newtonian corrections the interaction be…
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…
Sharpening the dark matter signature in gravitational waveforms II: Numerical simulations with the NbodyIMRI code
Bradley J. Kavanagh, Theophanes K. Karydas, Gianfranco Bertone +2
Future gravitational wave observatories can probe dark matter by detecting the dephasing in the waveform of binary black hole mergers induced by dark matter overdensities. Such a d…
Sharpening the dark matter signature in gravitational waveforms I: Accretion and eccentricity evolution
Theophanes K. Karydas, Bradley J. Kavanagh, Gianfranco Bertone
Dark matter overdensities around black holes can alter the dynamical evolution of a companion object orbiting around it, and cause a dephasing of the gravitational waveform. Here,…
Disks, spikes, and clouds: distinguishing environmental effects on BBH gravitational waveforms
Philippa S. Cole, Gianfranco Bertone, Adam Coogan +5
Future gravitational wave interferometers such as LISA, Taiji, DECIGO, and TianQin, will enable precision studies of the environment surrounding black holes. In this paper, we stud…
