Title: Probing Dark Matter and Dark Energy from Our Cosmic Neighborhood
Abstract:
The standard cosmological model, while remarkably successful, faces tensions. A major challenge lies in accurately mapping the distribution of dark matter and reconstructing velocities, as traditional mass and dynamical estimation methods often rely on oversimplified assumptions. In this talk, I will show how we can use the data from the Local Universe (CosmicFlow4) from binary galaxy systems like the Local Group, CenA/M83, to massive clusters such as Coma to address discrepancies in mass estimates. With high-precision data from Gaia and forthcoming surveys such as DESI and 4MOST, together with new I will show how the next generation of dark matter and dark energy constraints will face these issues
