Shielding linearised gravity
R. Beig, P. T. Chruściel
We present an elementary argument that one can shield linearised gravitational fields using linearised gravitational fields. This is done by using third-order potentials for the me…
Existence and uniqueness of Bowen-York Trumpets
G. Waxenegger, R. Beig, N. Ó Murchadha
We prove the existence of initial data sets which possess an asymptotically flat and an asymptotically cylindrical end. Such geometries are known as trumpets in the community of nu…
Late time behaviour of the maximal slicing of the Schwarzschild black hole
R. Beig, N. Ó Murchadha
A time-symmetric Cauchy slice of the extended Schwarzschild spacetime can be evolved into a foliation of the -region of the spacetime by maximal surfaces with the requireme…
The isometry groups of asymptotically flat, asymptotically empty space-times with timelike ADM four-momentum
R. Beig, P. T. Chruściel
We give a complete classification of all connected isometry groups, together with their actions in the asymptotic region, in asymptotically flat, asymptotically vacuum space--times…
TT-tensors and conformally flat structures on 3-manifolds
R. Beig
We study transverse-tracefree (TT)-tensors on conformally flat 3-manifolds . The Cotton-York tensor linearized at maps every symmetric tracefree tensor into one which is…
Initial Data for General Relativity with Toroidal Conformal Symmetry
Robert Beig, Sascha Husa
A new class of time-symmetric solutions to the initial value constraints of vacuum General Relativity is introduced. These data are globally regular, asymptotically flat (with poss…
