Excitation of scalar quasi-normal modes from boson clouds
Enrico Cannizzaro, Marco Palleschi, Laura Sberna +2
Massive scalar fields on black hole backgrounds generally admit two families of modes: quasi-bound states (QBS) and quasinormal modes (QNM). We demonstrate the orthogonality betwee…
Dynamical quasinormal mode excitation
Marina De Amicis, Enrico Cannizzaro, Gregorio Carullo +1
We study the dynamical excitation of quasinormal modes (QNMs) through the plunge, merger and ringdown of an extreme-mass-ratio-inspiral into a Schwarzschild black hole, for generic…
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…
