Radiating black hole solutions in Einstein-Gauss-Bonnet gravity
Alfredo E. Dominguez, Emanuel Gallo
In this paper, we find some new exact solutions to the Einstein-Gauss-Bonnet equations. First, we prove a theorem which allows us to find a large family of solutions to the Einstei…
Newtonian limit of the singular f(R) gravity in the Palatini formalism
A. E. Dominguez, D. E. Barraco
Recently D. Vollick [Phys. Rev. D68, 063510 (2003)] has shown that the inclusion of the 1/R curvature terms in the gravitational action and the use of the Palatini formalism offer…
A gravitational memory effect in "boosted" black hole perturbation theory
Reinaldo J. Gleiser, Alfredo E. Dominguez
Black hole perturbation theory, or more generally, perturbation theory on a Schwarzschild bockground, has been applied in several contexts, but usually under the simplifying assump…
Superselection Sectors in Asymptotic Quantization of Gravity
Alfredo E. Dominguez, Carlos N. Kozameh, Malcolm Ludvigsen
Using the continuity of the scalar (the mass aspect) at null infinity through we show that the space of radiative solutions of general relativity can be thought of a fi…
