Resumen
Descripción
Se presenta un resumen del modelo estándar de cosmología, desde su origen hasta hoy. Se discuten primero los resultados observacionales recientes, entre los cuales están las diversas mediciones de la RCF, de super-novas tipo Ia y catálogos de galaxias; se mencionan resultados importantes de las simulaciones cosmológicas de N-cuerpos. A continuación se presenta una parte teórica que analiza los modelos de FRW, y enseguida se discuten los problemas de la constante cosmológica, de inflación y de oscilaciones acústicas. Finalmente se presentan las ideas generales de quintaesencia.
A summary of the standard model of cosmology from it origins until today are presented. Firstly, recent observational results, among which are: the various measurements of the RCF, type Ia supernovae, galaxies catalog; significant results of N-body cosmological simulations are reported. Right after there is a theoretical part which analyzes the FRW models. Following, the problem of the cosmological constant, inflation and acoustic oscillations are discussed. Finally, the general ideas behind quintessence are presented.
