"Impact of Primordial Non-Gaussianities (fnl) on the effective dark energy equation of state."
Trindade, Arlindo (CAUP)

Primordial Non-Gaussianities constitute a powerful tool to test different inflationary scenarios, as well as to probe the physical processes in the early Universe. The abundance of galaxy clusters is very sensitive to deviation from Gaussianity in the primordial density perturbations, making it a powerful tool to test non-Gaussian initial conditions. Making use of this fact, we have investigated the effect that Primordial Non-Gaussianities may have on the reconstruction of the effective dark energy equation of state.
