On limit behavior of quasi-local mass for ellipsoids at spatial infinity
Xiaokai He, Leong-Fai Wong, Naqing Xie
We discuss the spatial limit of the quasi-local mass for certain ellipsoids in an asymptotically flat static spherically symmetric spacetime. These ellipsoids are not nearly round…

Superradiant scattering by a black hole binary
Leong Khim Wong
I present evidence of a novel guise of superradiance that arises in black hole binary spacetimes. Given the right initial conditions, a wave will be amplified as it scatters off th…

Effective field theory for black holes with induced scalar charges
Leong Khim Wong, Anne-Christine Davis, Ruth Gregory
While no-hair theorems forbid isolated black holes from possessing permanent moments beyond their mass, electric charge, and angular momentum, research over the past two decades ha…
