Correlaciones entre sistemas del Universo Local y el Fondo de Radiación Cósmica
Abstract
In this paper we show some preliminary results of a work in progress, which is aimed to analyse the correlation between the fluctuations in the Cosmic Microwave Background radiation and structure in the Local Uni- verse. We concentrate here on large-scale regions corresponding to future virialized superstructures. For this purpose, we construct appropriate maps with SDSS data and WMAP maps publicly available using HEALPix soft- ware. We use a two-point cross-correlation function analysis, finding signal at different scales, which shows contribution from distinct structures.
