Black Holes as Frequency-Dependent Filters of Stochastic Gravitational Waves
Sefi Katznelson, Aidan Minger, Stefano Profumo
Black holes ring when perturbed, whereas their response to a stationary gravitational-wave background is a real-frequency scattering problem, not a source of additional quasi-norma…
High-frequency gravitational wave transients from superradiance
Henry Su, Lucas Brown, Christopher Ewasiuk +1
Ultralight bosons can form macroscopic gravitational-atom clouds around rotating black holes via superradiance, sourcing quasi-monochromatic gravitational waves through level trans…
Quantum Tunneling of Primordial Black Holes to White Holes: Rates, Constraints, and Implications for Fast Radio Bursts
Christopher Ewasiuk, Stefano Profumo
We calculate the present-day and cosmological volumetric rate of primordial black hole (PBH) quantum tunneling events to white holes, incorporating the competition between Hawking…
Dark-sector modifications to Kerr and Reissner-Nordstrom black hole evaporation
Christopher Ewasiuk, Stefano Profumo
We present a comprehensive comparative analysis of the evaporation dynamics of Schwarzschild, Kerr, and Reissner- Nordstrom black holes, focusing on the evolution of their mass, ch…
