Estudiando las estructuras a gran escala del Universo con la teor\'ia de perturbaciones no lineal
Abstract
The Large-Scale Structure (LSS) of the Universe provides valuable information for modern cosmology. The future redshift surveys, as DESI (Dark Energy Spectroscopic Instrument), will measure millions of galaxies and quasars, which allows to measure the history expansion and the growth factor. In this work, we present the theoretical model of the matter power spectrum and the redshift space multipoles of the galaxy power spectrum. We compute the spectrum using different methods as 1-loop Standard Perturbation Theory, Effective Field Theory and the Infrarred resummations.
