Dark Energy: developing theoretical models and confronting them against observations.
This research project aims to the develop theoretical models to explain Dark Energy, and to test these models against observations of the large scale structure of the universe and of supernovae of type Ia. From the theoretical point of view, the project aims to develop models based on scalar fields, the parameterization of the redshft dependece of the equation of state of the Dark Energy fluid, as well as the modelling of the non linear evolution of density fluctuations on small scales. From the observational point of view, these models will be tested against the most recent data available in the literature: supernovae (SNe IA) at high redshift, Baryon Acoustic Oscillation, Hubble parameter as a function of the redshift and, last but not least, the CMB anisotropy data.
