Evolution of diffuse scalar clouds around binary black holes
Leong Khim Wong
The use of modern effective field theory techniques has sparked significant developments in many areas of physics, including the study of gravity. Case in point, such techniques ha…
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…
Modelling the Milky Way's globular cluster system
James Binney, Leong Khim Wong
We construct a model for the Galactic globular cluster system based on a realistic gravitational potential and a distribution function (DF) analytic in the action integrals. The DF…
