We perform n-body simulations for models with a DE component. Besides of DE with constant negative w=p/ρ≥−1, we consider DE due to scalar fields, self-interacting through RP or SUGRA potentials. According to our post-linear analysis, at z = 0, DM power spectra and halo mass functions do not depend on DE nature. This is welcome, as ΛCDM fits observations. Halo profiles, instead, are denser than ΛCDM...

The next generation mass probes will obtain information on non‐linear power spectra P(k, z) and their evolution, allowing us to investigate the nature of Dark Energy. To exploit such data we need high‐precision simulations, extending at least up to scales of k≃ 10 h Mpc−1, where the effects of baryons can no longer be neglected. In this paper, we present a series of large scale hydrodynamical simulations...
