Precision cosmology with exact inhomogeneous solutions of General Relativity: the Szekeres models
Marie-Noëlle Célérier
The exact Friedman solution to the field equations of General Relativity (GR) describing a homogeneous and isotropic universe together with its linear and higher-order perturbation…

Gravitational collapse of anisotropic cylindrical shearfree fluids with new exact interior solutions of GR
Marie-Noëlle Célérier, Nilton O. Santos
We present a study of shearfree gravitational collapse using cylindrically symmetric spacetimes whose interior is a non-rotating dissipative fluid bounded by a cylindrical hypersur…

Interior spacetimes sourced by stationary differentially rotating irrotational cylindrical fluids: anisotropic pressure
Marie-Noëlle Célérier
In a recent series of papers new exact analytical interior spacetimes sourced by stationary rigidly rotating cylinders of fluids have been displayed. A fluid with an axially direct…
