Recovery of the Power Spectrum of Mass Fluctuations from Observations of the Lyα Forest
Recovery of the Power Spectrum of Mass Fluctuations from Observations of the Lyα Forest
We present a method to recover the shape and amplitude of the power spectrum of mass fluctuations, P(k), from observations of the high-redshift Lyα forest. The method is motivated by the physical picture that has emerged from hydrodynamic cosmological simulations and related semianalytic models, in which typical Lyα forest lines …
