ELUCID: Exploring the Local Universe with reConstructed Initial Density field

Abstract:

Simulating the evolution of the local universe is important for studying galaxies and the intergalactic medium in a way free of cosmic variance. I will describe a method to reconstruct the initial linear density field from an input non-linear density field, employing the Hamiltonian Markov Chain Monte Carlo (HMC) algorithm combined with Particle Mesh (PM) dynamics. The power of this method is tested using high-resolution cosmological simulations. Preliminary results obtained from applying the method to real observational data are described.
