[Le fond diffus peut-il devoiler la topologie de l'univers ?]
Cet article résume les progrès récents concernant le développement des outils permettant d'étudier la signature topologique de l'univers dans le fond diffus cosmologique. Les différentes signatures de la topologie et les contraintes observationnelles sont décrites. Pour finir, la possibilité de dévoiler la structure topologique de notre univers est discutée.
This article summarizes recent progress in the development of tools to study the topology of the universe with the cosmic microwave background. The different signatures of the topology and observational constraints are described. The ability of future experiments to reveal the topological structure of our universe is then discussed.
