Minimally parametric power spectrum reconstruction from the Lyman α forest
Minimally parametric power spectrum reconstruction from the Lyman α forest
Current results from the Lyman alpha forest assume that the primordial power spectrum of density perturbations follows a simple power law form, with running. We present the first analysis of Lyman alpha data to study the effect of relaxing this strong assumption on primordial and astrophysical constraints. We perform a …
