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…
Axion dissipation in conductive media and neutron star superradiance
Thomas F. M. Spieksma, Enrico Cannizzaro
In axion electrodynamics, magnetic fields enable axion-photon mixing. Recent proposals suggest that rotating, conductive plasmas in neutron star magnetospheres could trigger axion…
Environmental effects in extreme mass ratio inspirals: perturbations to the environment in Kerr
Conor Dyson, Thomas F. M. Spieksma, Richard Brito +2
Future gravitational wave observatories open a unique avenue to study the environments surrounding black holes. Intermediate or extreme mass ratio inspirals will spend thousands to…
