CENTRA Seminar - Dark Couplings - 1 junho 2017

The discovery that our Universe is currently accelerating has propelled various possible explanations, one candidate being scalar field dark energy. However, this light scalar field must, in principle, interact with the rest of the world including dark matter. In this talk we will explore a number of possible ways of how dark energy can couple with dark matter and electromagnetism and design ways to test and constrain these couplings with cosmological observations.
