Constraining inflation with future galaxy redshift surveys

摘要: With future galaxy surveys, a huge number of Fourier modes the distribution large scale structures in Universe will become available. These are complementary to those CMB and can be used set constraints on models early universe, such as inflation. Using MCMC analysis, we compare power with that combination survey data, constrain spectrum primordial fluctuations generated during We base our analysis Planck satellite spectroscopic redshift configuration parameters close Euclid mission examples. first consider slow-roll inflation, show inclusion structure data improves by nearly halving error bars scalar spectral index its running. If attempt reconstruct inflationary single-field potential, similar conclusion reached characterizing potential. then study features spectrum. In particular, ringing produced break potential oscillations axion monodromy. Adding more than factor two. monodromy there small amplitude frequency momentum space undetected alone but measured including surveys analysis.
