Evolución cosmológica de un modelo de energía oscura con interacción no lineal.
Resumen
En este trabajo consideramos un modelo holográfico de energía oscura junto con una interacción no lineal nentre la componente de energía oscura y la de materia oscura en un universo plano tipo FRW. En este contexto, se analiza la evolución cosmológica del universo teniendo en cuenta el comportamiento de los parámetros de desaceleración q y de la ecuación de estado wΛ. A partir de este análisis se deduce que el universo presenta una fase de expansión acelerada en tiempos tardíos. Se observa también que en este escenario la densidad de energía oscura presenta una singularidad tipo Big Rip en el futuro. Finalmente, comparamos el modelo con los datos disponibles actualmente para H(z).
