The Lyman-alpha forest according to LUQAS
Abstract
We use the LUQAS sample of 27 high resolution, high signal-to-noise QSO absorption spectra (Kim et al. 2004) and the results from Croft et al. (2002) together with a suite of high-resolution hydro-dynamical simulations run with the GADGET-II code, to infer the linear dark matter power spectrum on scales of \~ 0.3-30 Mpc at z=2.125 and at z=2.72.
