Mass and angular momenta of Kerr-anti-de Sitter spacetimes
Nathalie Deruelle
We briefly review how to compute the mass and angular momenta of rotating, asymptotically anti-de Sitter spacetimes in Einstein-Gauss-Bonnet theory of gravity using superpotentials…
Bouncing universes and their perturbations: remarks on a toy model
Nathalie Deruelle
Friedmann-Lemaitre universes driven by a scalar field, spatially closed and bouncing, were recently studied by Martin and Peter in [1], with the conclusion that the spectrum of the…
On the quasi-linearity of the Einstein- "Gauss-Bonnet" gravity field equations
Nathalie Deruelle, John Madore
We review some properties of the Einstein-"Gauss-Bonnet" equations for gravity--also called the Einstein-Lanczos equations in five and six dimensions, and the Lovelock equations in…
Linearized gravity on branes: from Newton's law to cosmological perturbations
Nathalie Deruelle
We review here how Newton's law can be approximately recovered in the simple, "paradigmatic", case of a flat -symmetric brane in a 5-D anti-de Sitter bulk. We then comment on…
Stars on branes: the view from the brane
Nathalie Deruelle
We consider spherically symmetric matter configurations on a four dimensional "brane" embedded in a five dimensional -symmetric "bulk". We write the junction conditions betwee…
Cosmic microwave background anisotropies seeded by coherent topological defects : a semi-analytic approach
Jean-Philippe Uzan, Nathalie Deruelle, Alain Riazuelo
We consider a perfectly homogeneous, isotropic and spatially flat universe which undergoes a sudden phase transition producing topological defects. We assume that these defects for…
