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…
Gravitational-wave tails and memory effect for mergers in astrophysical environments
Qassim Alnasheet, Vitor Cardoso, Francisco Duque +1
Gravitational waves from the coalescence of compact objects carry information about their dynamics and the spacetime in regions where they are evolving. In particular, late-time ta…
Prospects for EMRI/MBH parameter estimation using Quasi-Periodic Eruption timings: short-timescale analysis
Joheen Chakraborty, Lisa V. Drummond, Matteo Bonetti +11
Quasi-Periodic Eruptions (QPEs) are luminous, recurring X-ray outbursts from galactic nuclei, with timescales of hours to days. While their origin remains uncertain, leading models…
Black hole spectroscopy: from theory to experiment
Emanuele Berti, Vitor Cardoso, Gregorio Carullo +70
The "ringdown" radiation emitted by oscillating black holes has great scientific potential. By carefully predicting the frequencies and amplitudes of black hole quasinormal modes a…
Black hole spectroscopy in environments: detectability prospects
Thomas F. M. Spieksma, Vitor Cardoso, Gregorio Carullo +2
The ringdown phase following a binary black hole coalescence is a powerful tool for measuring properties of the remnant black hole. Future gravitational wave detectors will increas…
Gravitational Waves from Accretion Disks: Turbulence, Mode Excitation and Prospects for Future Detectors
Chen Yuan, Vitor Cardoso, Francisco Duque +1
We study gravitational-wave emission by turbulent flows in accretion disks around spinning black holes or neutron stars. We aim to understand how turbulence can stochastically exci…
