With commuting Killing vectors, the lapse and shift of one Killing vector are constants along the other
Niall O Murchadha
Given an d-dimensional manifold with two commuting Killing vectors, together with an d - 1 dimensional submanifold in which one of the Killing vectors lies, then the lapse and shif…

Equilibrium initial data for moving puncture simulations: The stationary 1+log slicing
T. W. Baumgarte, Z. B. Etienne, Y. T. Liu +4
We propose and explore a "stationary 1+log" slicing condition for the construction of solutions to Einstein's constraint equations. For stationary spacetimes, these initial data wi…

Some remarks on the size of bodies and black holes
Gregory J. Galloway, Niall O'Murchadha
We consider the application of stable marginally outer trapped surfaces to problems concerning the size of material bodies and the area of black holes. The results presented extend…
