A hierarchical analysis of 69 GWTC-3 black-hole merger candidates yields an effective compactness consistent with C=0.5 and no evidence for a low-compactness exotic population.
Tidal Love numbers of regular black holes are generically nonzero, model-dependent, and can acquire logarithmic scale dependence at higher perturbative orders.
Semi-analytic waveform model for scalar environments around black hole binaries is validated against numerical relativity and applied to LIGO-Virgo-KAGRA data to obtain upper limits on scalar densities with tentative evidence in GW190728.
Presents cavity-based effective descriptions for scalar radiation from black holes and modified models, linking them to wave profiles and accumulated phase shifts for detecting small deviations from classical behavior.
A symmetry-based litmus test identifies when physical systems governed by second-order ODEs possess ladder structures and constructs them, linking supersymmetric quantum mechanics to Kerr black-hole tidal responses.
