Outline of Final Research Achievements |
We develop a new framework of gravitational N-body simulations that enable to conduct numerical simulations and their post analysis seamlessly. By combining a halo finding code with three-dimensional positions of simulation particles and that of cosmological N-body simulation, it becomes possible to reduce the data size for raw particle data significantly. We also made it possible to download the big dataset of halo/subhalo merger trees by means of database system. Each user can select properties downloaded and ranges of their value, which enables to download fast.
