Ecuación de dínamo cosmológica bajo teoría de perturbaciones cosmológicas a primer orden
No full textilustracionesEn este trabajo se pretende dar una introducción a las perturbaciones cosmológicas y aplicaciones desde el punto de vista de la Relatividad numérica, en particular se muestra como se pueden aplicar estas perturbaciones al formalismo 3+1. Las perturbaciones cosmológicas se dan a primer orden sobre la solución espacialmente plana de Friedman-Lemaitre-Robertson-Walker (FLRW), esto con miras a obtener la ecuación de dínamo cosmológico, bajo la aproximación de dínamo cinemático, para poder estudiar la evolución de los campos magnéticos primordiales y su amplificación. También se mostrará el estudio computacional de perturbaciones cosmológicas a partir de la Relatividad Numérica haciendo uso del software Einstein Toolkit, se hace énfasis en FLRWSolver para la solución numérica de las ecuaciones de campo de Einstein desde el punto de vista cosmológico. (Texto tomado de la fuente)This thesis aims to give an introduction to cosmological perturbations and their applications from the point of view of numerical relativity, in particular it shows how these perturbations can be applied to the 3+1 formalism. The cosmological perturbations are given up to first order on the spatially flat Friedman-Lemaitre-Robertson-Walker (FLRW) solution, this looking to obtaining the cosmological dynamo equation, under the kinematic-dynamo approximation, in order to study the evolution of primordial magnetic fields and their amplification. The computational study of cosmological perturbations from Numerical Relativity will also be shown using the Einstein Toolkit software, emphasizing FLRWSolver for the numerical solution of the Einstein field equations from the cosmological point of view.MaestríaMagíster en Ciencias - AstronomíaGravitación, Relatividad General, Cosmologia, Relatividad Numéric
