Abstract:  I will introduce recent results from the Aemulus project, which has a goal to perform precision emulation of galaxy survey observables based on high-resolution N-body simulations. This suite of simulations spans the range of parameter space allowed by the latest CMB and large scale structure observations.I will present an overview of the simulations, the emulator for halo mass function and galaxy correlation function. In particular, I will focus on the modeling of the two-point clustering of galaxies in real and redshift space. The result will reveal the power to constrain cosmology with the information at non-linear scale.
