Abstract

Recently, technological advances have allowed previously unthinkable astronomical observations. This means an unprecedented flow of high-quality data on the universe. The new observations, coupled with a theoretical framework in constant evolution, are turning cosmology in one of the most exciting frontiers of science. Nevertheless, despite these efforts, many questions still challenge us: we do not know what types of substances make up to 95% of the universe; we do not know what is dark matter; we have little knowledge about the epoch of formation of the first objects; we are not sure if the cosmic microwave background radiation can be reduced to a few cosmological parameters, or whether other astrophysical mechanisms leave an imprint on the observed anisotropies; last but not least, is remains a deep mystery the cause of the recent acceleration of the universe. These are the basic problems of modern cosmology. The strong connection between them means that breakthroughs in any of these areas walk hand-in-hand. (AU)
