Scaling up the extrinsic curvature in asymptotically flat gravitational initial data: Generating trapped surfaces

Shan Bai, Niall Ó Murchadha

The existence of the initial value constraints means that specifying initial data for the Einstein equations is non-trivial. The standard method of constructing initial data in the…

Scaling up the extrinsic curvature in gravitational initial data

Shan Bai, Niall Ó Murchadha

Vacuum solutions to the Einstein equations can be viewed as the interplay between the geometry and the gravitational wave energy content. The constraints on initial data reflect th…

Intrinsic time gravity and the Lichnerowicz-York equation

Niall Ó Murchadha, Chopin Soo, Hoi-Lai Yu

We investigate the effect on the Hamiltonian structure of general relativity of choosing an intrinsic time to fix the time slicing. 3-covariance with momentum constraint is maintai…
