Cosmology

This research line focuses on the theoretical and phenomenological study of the Universe from its earliest stages to its present large-scale dynamics. It includes topics such as the Early Universe, large-scale structure formation, and the late-time accelerated expansion, together with the investigation of topological defects, inflation, dark energy, and dark matter scenarios motivated by particle physics. Particular emphasis is placed on the interplay between cosmology, particle physics, and gravitation, using a wide variety of theoretical methods and observational tests. Through these efforts, this research line seeks to advance our understanding of the origin, composition, and evolution of the Universe, while strengthening the links between fundamental physics and observable cosmological phenomena.
