Cosmological hydrodynamical simulations of clustering dark energy with Nefertiti
Linda Blot, Théo Gayoux, Fabian Schmidt +2
We present the first cosmological simulations that consistently include nonlinear clustering dark energy evolved as a fluid with the numerical hydrodynamics code Nefertiti. Dark en…

Euclid: Systematic uncertainties from the halo mass conversion on galaxy cluster number count data analyses
T. Gayoux, P. -S. Corasaniti, T. R. G. Richardson +153
The large catalogues of galaxy clusters expected from the Euclid survey will enable cosmological analyses of cluster number counts that require accurate cosmological model predicti…

Euclid preparation LXIII. Simulations and nonlinearities beyond CDM. 2. Results from non-standard simulations
Euclid Collaboration, G. Rácz, M. -A. Breton +275
The Euclid mission will measure cosmological parameters with unprecedented precision. To distinguish between cosmological models, it is essential to generate realistic mock observa…
