Self-acceleration of Hardening Binaries
Giovanni Maria Tomaselli, Thomas F. M. Spieksma
A Keplerian binary immersed in a bath of lighter particles hardens by ejecting them through gravitational slingshots. This process drives, for example, the evolution of supermassiv…
The Depletion of Collisionless Dark Matter Spikes
Charlie Sharpe, Yonadav Barry Ginat, Thomas F. M. Spieksma +1
Dense concentrations of dark matter (DM) surrounding black holes provide a compelling opportunity to probe the nature of DM. In the classic Gondolo-Silk model, the adiabatic growth…
Gravitational Atom Spectroscopy
Matteo Della Rocca, Thomas F. M. Spieksma, Francisco Duque +2
Black holes in our Universe are rarely truly isolated, being instead embedded in astrophysical environments such as plasma or dark matter. A particularly intriguing possibility is…
Exploring Black Hole Environments
Thomas F. M. Spieksma
The past decade has transformed our ability to observe the Universe. Via gravitational waves, merging black holes and neutron stars can now be directly detected, offering unprecede…
Total absorption of tailored incoming signals by black holes
Furkan Tuncer, Vitor Cardoso, Rodrigo Panosso Macedo +1
We uncover a new class of phenomena in gravitational physics, whereby resonances in the complex plane can be excited via tailored time-dependent scattering. We show that specific f…
In the grip of the disk: dragging the companion through an AGN
Thomas F. M. Spieksma, Enrico Cannizzaro
Active galactic nuclei (AGN) have been proposed as environments that can facilitate the capture of extreme-mass-ratio binaries and accelerate their inspiral beyond the rate expecte…
