En esta tesis se han explorado posibles extensiones del Modelo Estandar de la Cosmolog??a. Hemosobtenido las predicciones teoricas de los modelos considerados y sus principales caracter??sticas. Losresultados presentados estan basados en tres proyectos principales en los que he participadoconjuntamente con mi supervisora, Mariam Boudmadi Lopez, y otros colaboradores. Estos proyectosenfocan tres areas diferentes de investigacion en la Cosmolog??a actual: teor??as metricas de gravedadmodificada…

Pre-inflation from the multiverse: can it solve the quadrupole problem in the cosmic microwave background?
- PhysicsThe European physical journal. C, Particles and fields
- 2018
A quantized toy model of a universe undergoing eternal inflation is analyzed using a quantum-field-theoretical formulation of the Wheeler–DeWitt equation to lead to the picture that the eternally inflating universe is converted to a multiverse in which sub-universes are created and exhibit a distinctive phase in their evolution before reaching an asymptotic de Sitter phase.
Direct constraints on minimal supersymmetry from Fermi-LAT observations of the dwarf galaxy Segue 1
