On the covariance of scalar averaging and backreaction in relativistic inhomogeneous cosmology
Asta Heinesen, Pierre Mourier, Thomas Buchert
We introduce a generalization of the 4-dimensional averaging window function of Gasperini, Marozzi and Veneziano (2010) that may prove useful for a number of applications. The cova…
Lagrangian theory of structure formation in relativistic cosmology. V. Irrotational fluids
Yong-Zhuang Li, Pierre Mourier, Thomas Buchert +1
We extend the general relativistic Lagrangian perturbation theory, recently developed for the formation of cosmic structures in a dust continuum, to the case of model universes con…
Cosmological backreaction and its dependence on spacetime foliation
Thomas Buchert, Pierre Mourier, Xavier Roy
The subject of cosmological backreaction in General Relativity is often approached by coordinate-dependent and metric-based analyses. We present in this letter an averaging formali…
