Physical Properties of the Lyα Forest in a Cold Dark Matter Cosmology
We discuss the origin and physical nature of the Lyα forest absorption systems as found in hydrodynamical simulations of the intergalactic medium (IGM) in a standard cold dark matter cosmology (Ω = 1, H0 = 50 km s-1 Mpc-1, σ8 = 0.7). The structures of the systems that give rise …
