Welcome to the Cosmology and Gravitation Group website!
Our research focuses on exploring and identifying potential signatures of alternative models to General Relativity, both at the cosmological scale and within compact objects. Additionally, within the framework of General Relativity, we investigate possible signatures from compact objects composed of non-baryonic matter.
