Cosmic Magnification - A New Window to Cosmology
The unknown nature of dark matter and dark energy represent two of the most puzzling problems in contemporary physics. Observational guidance is essential to constrain the parameter space of possible dark matter candidate particles and to test models of modified gravity. Even more importantly, only cosmological observations seem to be able to shed light on the mystery of dark energy, by directly measuring its energy density as function of redshift. This proposal is aimed at establishing a new cosmological probe - cosmic magnification - that will help to make progress in answering these questio
