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…
Primordial non-Gaussianity in density fluctuations
F. Fraschetti, J. M. Alimi, J. Courtin +1
We present N-body cosmological numerical simulations including a primordial non-Gaussianity in the density fluctuation field quantified by the non-linear parameter . We hav…
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…
