Probing Dynamical Dark Energy with Press-Schechter Mass Functions

Measurement of accelerated expansion in the Universe led to propose a new cosmic fluid as its cause: dark energy. Its various incarnations offer a wealth of models whose relevance it is important to discriminate via contacts with observations. I will present my investigations on the influence of dynamical dark energy models on the formation of non-linear dark matter structures. In particular, I will focus on structures traced by the mass function of dark matter haloes.
