Abstract
An invariant definition of mass in asymptotically de-Sitter space-times is given that relies on the
existence of a time-like Killing vector on a sphere surrounding the mass but does not require going
to an asymptotic region. In particular the mass can be calculated exactly on a sphere inside the
cosmological horizon. The formalism requires varying the background metric solution by a perturbation that satisfies the linearized equations of motion but need not share the Killing symmetry of
the solution and is therefore applicable when a gravitational wave within the cosmological horizon
perturbs a background metric with a time-like Killing vector.
