Introducing the Dark Energy Universe Simulation Series (DEUSS)
Y. Rasera, J-M. Alimi, J. Courtin +4
In this "Invisible Universe" proceedings, we introduce the Dark Energy Universe Simulation Series (DEUSS) which aim at investigating the imprints of realistic dark energy models on…
Imprints of dark energy on cosmic structure formation: II) Non-Universality of the halo mass function
J. Courtin, Y. Rasera, J. -M. Alimi +3
The universality of the halo mass function is investigated in the context of dark energy cosmologies. This widely used approximation assumes that the mass function can be expressed…
Imprints of Dark Energy on Cosmic Structure Formation I) Realistic Quintessence Models and the Non-Linear Matter Power Spectrum
J. -M. Alimi, A. Fuzfa, V. Boucher +3
Dark energy as a quintessence component causes a typical modification of the background cosmic expansion, which in addition to its clustering properties, can leave a potentially di…
A cosmological test for general relativity
Vincent Boucher
The effect of spatial variations of the Newton constant on the cosmic microwave background is studied. Constraints on the strong equivalence principle violation at the recombinatio…
Primordial constraint on the spatial dependence of the Newton constant
V. Boucher, J. -M. Gerard, P. Vandergheynst +1
A Nordtvedt effect at cosmological scales affects the acoustic oscillations imprinted in the cosmic microwave background. The gravitational baryonic mass density of the universe is…
Cosmic microwave background constraints on the strong equivalence principle
V. Boucher, J. -M. Gerard, P. Vandergheynst +1
We study the effect of a violation of the strong equivalence principle (SEP) on the cosmic microwave background (CMB). Such a violation would modify the weight of baryons in the pr…
