Over several years the cosmology group at LUTh has developed an active research program on the study of the formation and evolution of cosmic structures in the Universe and the nature of dark energy through high-performance numerical simulations.

To this purpose they have intensively worked on numerical coding and the implementation of parallelization schemes, which allow the science codes to efficiently run on super-computing systems and parallel machines. A major effort consisted in running the Dark Energy Universe Simulation Series (DEUSS) project, the largest series of high-resolution numerical simulations of realistic Dark Energy models with over a billion particles each. These simulations have provided several Tb of data which characterize the properties of the dark matter density field and those of dark matter halos between z=100 and z=0, over a range of scales from 3 kpc to 10 Gpc/h and halo mass interval from 2.5 10^10 to 1. 10^16 M_Sun.

These data are now available to the research community for the full science exploitation of the simulation results through the database DEUVO. To this purpose a consortium of national and international researchers has been organized with the intent of fostering project collaborations, facilitating access to the  numerical datasets and exchanging codes for data analysis. A number of projects have already started and we foresee more in the upcoming months.
