Description
In this talk I will focus on the probes of the dark sector.
I will present several non-trivial effects of cosmology on
the non-linear regime of structure formation. These imprints
have been studied in great details thanks to the large
volume of the "Full Universe Runs" simulations combined with
the high resolution of the "Dark Energy Universe Simulations
Series". I will highlight some results from horizon scale
down to halo scale: bias and dispersion of the angular
distance due to lensing, shift and damping of the BAOs,
non-universality of the dark matter halo mass function,
variation of the "sparsity" of dark matter halo profile. If
not accounted for properly, these non-linear imprints of
cosmology on structure formation could bias the cosmological
inference.
