Black-hole head-on collisions in higher dimensions
William G. Cook, Ulrich Sperhake, Emanuele Berti +1
The collision of black holes and the emission of gravitational radiation in higher-dimensional spacetimes are of interest in various research areas, including the gauge-gravity dua…
Light ring stability in ultra-compact objects
Pedro V. P. Cunha, Emanuele Berti, Carlos A. R. Herdeiro
We prove the following theorem: axisymmetric, stationary solutions of the Einstein field equations formed from classical gravitational collapse of matter obeying the null energy co…
Post-Kerr black hole spectroscopy
Kostas Glampedakis, George Pappas, Hector O. Silva +1
One of the central goals of the newborn field of gravitational wave astronomy is to test gravity in the highly nonlinear, strong field regime characterizing the spacetime of black…
Gravitational wave searches for ultralight bosons with LIGO and LISA
Richard Brito, Shrobana Ghosh, Enrico Barausse +5
Ultralight bosons can induce superradiant instabilities in spinning black holes, tapping their rotational energy to trigger the growth of a bosonic condensate. Possible observation…
Stochastic and resolvable gravitational waves from ultralight bosons
Richard Brito, Shrobana Ghosh, Enrico Barausse +5
Ultralight scalar fields around spinning black holes can trigger superradiant instabilities, forming a long-lived bosonic condensate outside the horizon. We use numerical solutions…
Synchronous frequencies of extremal Kerr black holes: resonances, scattering and stability
Maurício Richartz, Carlos A. R. Herdeiro, Emanuele Berti
The characteristic damping times of the natural oscillations of a Kerr black hole become arbitrarily large as the extremal limit is approached. This behavior is associated with the…
