摘要:
   In the standard cosmological model, LCDM model, dark matter and dark energy are two major components. However, whether there is interaction between dark matter and dark energy beyond gravity is unknown. Together with collaborators, I have developed the simulations and related codes for interacting dark energy model. Using N-body simulation, we have studied the impact of dark matter dark energy interaction on the structure formation. Combined with observations such as CMB, BAO, weak lensing and halo density profile, we have put strong constraints on the interaction between dark matter and dark energy.
