Asymptotic charges of a quadrupolar naked singularity
Edgar Gasperin, Mariem Magdy
The purpose of this article is to compute the asymptotic charges of a vacuum solution to the Einstein field equations describing a naked singularity with a non-vanishing quadrupole…
An invariant measure of deviation from Petrov type D at the level of initial data
Edgar Gasperin, Jarrod L. Williams
In this article, we describe a simple covariant characterisation of initial data sets which give rise to Petrov type D vacuum spacetime developments. As an application, we derive a…
An asymptotic systems approach for the good-bad-ugly model with application to general relativity
Miguel Duarte, Justin C. Feng, Edgar Gasperín +1
We employ an adapted version of Hörmander's asymptotic systems method to show heuristically that the standard good-bad-ugly model admits formal polyhomogeneous asymptotic solutions…
Numerical evolutions of the linearised conformal Einstein field equations in the inversion-Minkowski spacetime
Christian Peterson, Edgar Gasperín, Alex Vañó-Viñuales
Numerical evolutions of a system of equations close to null infinity in the geometric background of the inversion-Minkowski spacetime are performed. The evolved equations correspon…
