Spherical collapse of non-top-hat profiles in the presence of dark energy with arbitrary sound speed
R. C. Batista, H. P. de Oliveira, L. R. W. Abramo
We study the spherical collapse of non-top-hat matter fluctuations in the presence of dark energy with arbitrary sound speed. The model is described by a system of partial differen…
Bona-Massó slices of Reissner-Nordström spacetimes
Sean E. Li, Thomas W. Baumgarte, Kenneth A. Dennison +1
Motivated by recent numerical relativity simulations of charged black holes and their interactions, we explore the properties of common slicing conditions in Reissner-Nordström spa…
Quest for eternal oscillons
T. S. Mendonça, H. P. de Oliveira
Nonlinear field theories produce unstable but long-lived configurations known as oscillons. These structures have been studied with asymmetric and symmetric double-well potentials…
