Astrophysics, Cosmology, Gravitation

The Universe is all of space and time and its content, including stars, galaxies, black holes, the vacuum, and all other forms of matter and energy. The Astrophysics, Cosmology and Gravitation (ACG) group studies the physics of the Universe, from observations of astrophysical and cosmological phenomena, to the theories that describe it, but it also poses more fundamental questions related to the force of gravity. 

In particular, we in the ACG group investigate the evolution of the Universe from its earliest to its latest stages, i.e., an origin of primordial fluctuations, formation of structures and the current cosmic acceleration. This includes a study of relevant astrophysical processes, such as the intergalactic medium, the formation and evolution of galaxies, gravitational waves and the large-scale structure of the Universe; while at the fundamental level, we explore alternative theories of gravity that could help to understand a possible quantum nature of the gravitational interaction, and whose applications can be found in the cosmological context as well as in black hole physics and holography.
