Conformal geodesics and the hyperboloid at timelike infinity
Achilleas V. Koukas, Mariem Magdy, Juan A. Valiente Kroon
A description of scattering in asymptotically flat spacetimes that includes both radiation and massive asymptotic states requires control of the relation between null and timelike…
The space spinor formalism and estimates for spinor fields
Mariem Magdy, Juan A. Valiente Kroon
We show how the space spinor formalism for 2-component spinors can be used to construct estimates for spinor fields satisfying first order equations. We discuss the connection of t…
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…
Asymptotics of spin-0 fields and conserved charges on n-dimensional Minkowski spaces
Edgar Gasperín, Mariem Magdy, Filipe C. Mena
We use conformal geometry methods and the construction of Friedrich's cylinder at spatial infinity to study the propagation of spin- fields (solutions to the wave equation) on $…
Asymptotic charges for spin-1 and spin-2 fields at the critical sets of null infinity
Mariem Magdy, Juan A. Valiente Kroon
The asymptotic charges of spin-1 and spin-2 fields are studied near spatial infinity. We evaluate the charges at the critical sets where spatial infinity meets null infinity with t…
