Hetz Soto, Alexander Ulrich (Universidad de Chile, 2016)Supergravity inflation is considered in the context of the single-field effective field theory for scalar perturbations arising from multiple-field inflation.\\ \\ It is possible to deduce a single-field effective field ...

Scheihing Hitschfeld, Bruno Sebastián (Universidad de Chile, 2019)En esta tesis, mostramos cómo la estructura del paisaje del Universo primordial puede ser investigada a través de las propiedades de las perturbaciones de densidad primordiales responsables por el origen de las anisotropías ...

Riquelme Chamblas, Walter Esteban (Universidad de Chile, 2018)The standard model of cosmology has some problems in order to describe the early stages of the universe. The theory of Cosmic Inflation, a phase of accelerated exponential expansion, was conceived to solve the previous ...

Bravo Guerraty, Rafael Fernando (Universidad de Chile, 2021)In this thesis, we show how future cosmological observations can provide us access to unveil the mechanism responsible for the origin of the structure in our universe. The primordial perturbations sourced by quantum vacuum ...

Pradenas Márquez, Bastián (Universidad de Chile, 2019)In this thesis, theoretical aspects of observables thrown by cosmic inflation were studied. In the first work, hypothetical feature correlations were studied in the inflationary scalar spectrum with features in the tensorial ...
