Learning the Evolution of the Universe in N-body Simulations

Understand

Understanding the physics of large cosmological surveys down to small (nonlinear) scales will significantly improve our knowledge of the Universe.

• Large N-body simulations have been built to obtain predictions in the non-linear regime.
• However, N-body simulations are computationally expensive and generate large amount of data, putting burdens on storage.
• These data are snapshots of the simulated Universe at different times, and fine sampling is necessary to accurately save its whole history.
