Cmb improntas del modelo bianchi i : simulación en software con condiciones iniciales para el espectro de potencia del CMB.

Abstract

More than 30 years ago, the COBE (Cosmic Background Explorer) satellite was launched in order to analyze the microwave background radiation. This satellite made it possible to detect fluctuations of the order of 10-5 in temperature, and supported the standard cosmological model. . This model describes the universe through the Friedmann-Robertson-Walker metric, as a flat, homogeneous and isotropic universe, which has evolved from a dense and hot phase during which matter and radiation were in thermal equilibrium. . The CMB is the residual radiation of the photons of this first phase. However, this model presents problems when explaining data from the CMB, precisely its angular power spectrum, since it presents a smaller magnitude than that predicted by the standard model, this problem is mostly known as the quadrupole anomaly. And for this reason, it is necessary to resort to models that explain these anomalies. A family of models that carry out this explanation are the Bianchi models, which are based on a homogeneous universe, but not necessarily isotropic. In this project, simulations will be developed that take into account anisotropic line elements, such as the Bianchi I model, and observe their viability.
