Strong Lensing Group

Research Focus

Our goal is to use strong gravitational lensing observations to derive observational constraints on the nature of dark matter and its interplay with baryonic processes and quantify the role of magnetic fields in distant galaxies. If you are interested in joining us, contact Simona Vegetti.
