Colloquium:- Reconstructing Initial Conditions to Simulate the Cosmic Web
Exploring the Local Universe with the reConstructed Initial Density field(ELUCID) is a method to reconstruct the initial linear density field from an input nonlinear density field, employing the Hamiltonian Markov Chain(HMC) Monte Carlo algorithm combined with Particle-Mesh(PM) dynamics. The speaker’s talk will describe its application and the constrained N-body and gas simulations in the Sloan Digital Sky Survey(SDSS) volume. He will show how to use the reconstruction to understand galaxies and gas in the cosmic web, as well as the underlying physics.
