Observables in a lattice Universe
Jean-Philippe Bruneton, Julien Larena
We explore observables in a lattice Universe described by a recently found solution to Einstein field equations. This solution models a regular lattice of evenly distributed object…
Dynamics of a lattice Universe
Jean-Philippe Bruneton, Julien Larena
We find a solution to Einstein field equations for a regular toroidal lattice of size L with equal masses M at the centre of each cell; this solution is exact at order M/L. Such a…
Fab Four: When John and George play gravitation and cosmology
Jean-Philippe Bruneton, Massimiliano Rinaldi, Antonin Kanfon +3
Scalar-tensor theories of gravitation have recently regained a great interest after the discovery of the Chameleon mechanism and of the Galileon models. The former allows, in princ…
