Testing backreaction effects with observations
Julien Larena, Jean--Michel Alimi, Thomas Buchert +2
In order to quantitatively test the ability of averaged inhomogeneous cosmologies to correctly describe observations of the large scale properties of the Universe, we introduce a s…
Reinterpreting dark energy through backreaction: the minimally coupled morphon field
Julien Larena, Thomas Buchert, Jean-Michel Alimi
In the context of averaged cosmologies, the effective equations can be written in the form of "regional" Friedmannian equations with additional sources arising from the so-called b…
Reinterpreting quintessential dark energy through averaged inhomogeneous cosmologies
Julien Larena, Thomas Buchert, Jean-Michel Alimi
Regionally averaged relativistic cosmologies have recently been considered as a possible explanation for the apparent late time acceleration of the Universe. This contribution repo…
Big Bang nucleosynthesis in scalar tensor gravity: the key problem of the Li abundance
Julien Larena, Jean-Michel Alimi, Arturo Serna
Combined with other CMB experiments, the WMAP survey provides an accurate estimate of the baryon density of the Universe. In the framework of the standard Big Bang Nucleosynthesis…
