Coherent Selection of Critical Kasner Response
Yi-kun Li
A coherent wave component with extremely small initial self-energy can substantially change the first response of a contracting spacetime. We demonstrate this effect in Einstein--M…
Optimal Extension Regularity at the McVittie Event Horizon
Yi-kun Li
We determine the optimal local extension regularity of the future black-hole event horizon in the exact spatially flat McVittie solutions sourced by a positive cosmological constan…
Hair or a Boundary Source? Covariant Phase Space of a Static Type-I Black Hole
Yi-kun Li
We study the two-parameter static type-I vacuum black hole recently obtained from an electromagnetic seed by a nonlinear solution-generating map. Its parameter changes dimensio…
Relativistic Tidal Transitions of Saturated Kerr Boson Clouds
Yi-kun Li, Lang Cui
Rotating black holes can bind ultralight bosons in macroscopic clouds whose level structure is swept by the tidal field of a binary companion. Existing estimates of the resulting r…
Model-Agnostic Population Inference for Gravitational-Wave Astronomy: From LVK to LISA
Yi-kun Li, Cheng Cheng, Lang Cui +1
Inferring the intrinsic population of compact binary mergers is complicated by detector selection biases and measurement uncertainties. Traditional parametric methods are limited b…
