Bondi mass with a cosmological constant
Vee-Liem Saw
The mass loss of an isolated gravitating system due to energy carried away by gravitational waves with a cosmological constant was recently worked out, using the Newman-Pe…
Asymptotically simple spacetimes and mass loss due to gravitational waves
Vee-Liem Saw
The cosmological constant used to be a freedom in Einstein's theory of general relativity, where one had a proclivity to set it to zero purely for convenience. The signs of …
Peeling property and asymptotic symmetries with a cosmological constant
Vee-Liem Saw, Freeman Chee Siong Thun
This paper establishes two things in an asymptotically (anti-)de Sitter spacetime, by direct computations in the physical spacetime (i.e. with no involvement of spacetime compactif…
Mass loss due to gravitational waves with
Vee-Liem Saw
The theoretical basis for the energy carried away by gravitational waves that an isolated gravitating system emits was first formulated by Hermann Bondi during the 1960s. Recent fi…
Behaviour of asymptotically electro- spacetimes
Vee-Liem Saw
We present the asymptotic solutions for spacetimes with non-zero cosmological constant coupled to Maxwell fields, using the Newman-Penrose formalism. This extends a recent work…
Mass-loss of an isolated gravitating system due to energy carried away by gravitational waves with a cosmological constant
Vee-Liem Saw
We derive the asymptotic solutions for vacuum spacetimes with non-zero cosmological constant , using the Newman-Penrose formalism. Our approach is based exclusively on the physi…
Constructing vacuum spacetimes by generating manifolds of revolution around a curve
Vee-Liem Saw
We develop a general perturbative analysis on vacuum spacetimes which can be constructed by generating manifolds of revolution around a curve, and apply it to the Schwarzschild met…
A rotating universe outside a Schwarzschild black hole where spacetime itself non-uniformly rotates
Vee-Liem Saw
We study a non-uniformly rotating universe outside a Schwarzschild black hole by generating a time-dependent manifold of revolution around a straight line. In this simple model whe…
Curved traversable wormholes in (3+1)-dimensional spacetime
Vee-Liem Saw, Lock Yue Chew
We present the general method of constructing curved traversable wormholes in (3+1)-d spacetime and proceed to thoroughly discuss the physics of a zero tidal force metric without c…
