A new class of obstructions to the smoothness of null infinity
J. A. Valiente-Kroon
Expansions of the gravitational field arising from the development of asymptotically Euclidean, time symmetric, conformally flat initial data are calculated in a neighbourhood of s…
Can one detect a non-smooth null infinity?
Juan A. Valiente-Kroon
It is shown that the precession of a gyroscope can be used to elucidate the nature of the smoothness of the null infinity of an asymptotically flat spacetime (describing an isolate…
Conserved quantities in a black hole collision
S. Dain, J. A. Valiente-Kroon
The Newman-Penrose constants of the spacetime corresponding to the development of the Brill-Lindquist initial data are calculated by making use of a particular representation of sp…
Boost-rotation symmetric type D radiative metrics in Bondi coordinates
R. Lazkoz, J. A. Valiente Kroon
The asymptotic properties of the solutions to the Einstein-Maxwell equations with boost-rotation symmetry and Petrov type D are studied. We find series solutions to the pertinent s…
On Killing vector fields and Newman-Penrose constants
J. A. Valiente-Kroon
Asymptotically flat spacetimes with one Killing vector field are considered. The Killing equations are solved asymptotically using polyhomogeneous expansions (i.e. series in powers…
