Stochastic Limit of Growing Gravitational Wave Memory from Sources in the Early Universe and Astrophysical Sources
Lydia Bieri
We show that the stochastic background of gravitational wave memory of growing type leads to a fractional Brownian motion increasing at the order of for large where $\f…

Asymptotically Euclidean Solutions of the Constraint Equations with Prescribed Asymptotics
Lydia Bieri, David Garfinkle, James Isenberg +2
We demonstrate that in constructing asymptotically flat vacuum initial data sets in General Relativity via the conformal method, certain asymptotic structures may be prescribed a p…

Brill Waves with Slow Fall-Off Towards Spatial Infinity
Lydia Bieri, David Garfinkle, James Wheeler
We compute families of solutions to the Einstein vacuum equations of the type of Brill waves, but with slow fall-off towards spatial infinity. We prove existence and uniqueness of…
