    Descripción

    El Fondo Cósmico de Microondas (FCM) contiene la información estadística de las semillas primigenias que han dado lugar a la formación de todas las estructuras en el Universo. Su contrapartida natural en el Universo local es la distribución de las galaxias que surgen como resultado del crecimiento gravitatorio de aquellas fluctuaciones de densidad primigenias. La caracterización de la distribución de inhomogeneidades a gran escala en el Universo local proporciona una herramienta muy poderosa, y complementaria al FCM, para determinar el origen y el contenido energético del Universo, el ritmo de expansión del mismo durante la evolución cósmica, los detalles del proceso de formación de todas las estructuras a gran escala que observamos en el Universo hoy día. Esta es la página web del grupo de Cosmología con trazadores de la Estructura a Gran Escala (LSS de sus siglas en inglés), en el IAC.
