Abstract: On November 19, DESI released another set of papers based on year one data, thereby providing one of the most stringent tests to date of how gravity behaves at cosmic scales. Looking at galaxies and how they cluster over time reveals the growth of cosmic structure, which allows us to test theories of modified gravity and improve constraints on models of dark energy. Lucky for us, several researchers at the ICCUB are involved in the DESI collaboration. In this week's cosmology journal club, Héctor Gil Marín (co-leader of the new analysis) will talk about the latest results.
