9. Shan--Chen interacting vacuum cosmology

Natalie Hogg (IPhT CEA-Saclay)

5/5/22, 10:00 AM

In this talk, I will introduce a novel class of interacting vacuum dark energy models, based on recasting the equation of state originally developed in the context of lattice kinetic theory by Shan & Chen (1993) as the coupling between the vacuum and cold dark matter (CDM). This coupling allows the vacuum to evolve and is nonlinear around a characteristic energy scale ρ∗, changing into a...

19. Next-generation forecasts for screened and unscreened models of modified gravity

Santiago Casas (CosmoStat, CEA Paris-Saclay)

5/5/22, 10:40 AM

Next-generation galaxy surveys will provide an accurate determination of the growth of large scale structures (LSS) in the Universe as a function of scale and redshift, on top of improved determinations of the background geometry. This will allow us to test, with unprecedented precision, the predictions of the most popular modified gravity models proposed in the literature, that have not been...
