Sharp Signals of Boson Clouds in Black Hole Binary Inspirals
Daniel Baumann, Gianfranco Bertone, John Stout +1
Gravitational waves (GWs) are an exciting new probe of physics beyond the standard models of gravity and particle physics. One interesting possibility is provided by the so-called…
Ionization of Gravitational Atoms
Daniel Baumann, Gianfranco Bertone, John Stout +1
Superradiant instabilities may create clouds of ultralight bosons around rotating black holes, forming so-called "gravitational atoms." It was recently shown that the presence of a…
Gravitational Collider Physics
Daniel Baumann, Horng Sheng Chia, Rafael A. Porto +1
We study the imprints of new ultralight particles on the gravitational-wave signals emitted by binary black holes. Superradiant instabilities may create large clouds of scalar or v…
The Spectra of Gravitational Atoms
Daniel Baumann, Horng Sheng Chia, John Stout +1
We compute the quasi-bound state spectra of ultralight scalar and vector fields around rotating black holes. These spectra are determined by the gravitational fine structure consta…
