The Lyman‐α Forest as a Cosmological Tool

  title={The Lyman‐α Forest as a Cosmological Tool},
  author={D. Weinberg and R. Dav'e and N. Katz and J. Kollmeier},
We review recent developments in the theory of the Lyα forest and their implications for the role of the forest as a test of cosmological models. Simulations predict a relatively tight correlation between the local Lyα optical depth and the local gas or dark matter density. Statistical properties of the transmitted flux can constrain the amplitude and shape of the matter power spectrum at high redshift, test the assumption of Gaussian initial conditions, and probe the evolution of dark energy… Expand
