Shedding light on Dark Energy
Marcelle Soares-Santos, Fermilab
The accelerated expansion of the universe is a strong indication of physics beyond our current understanding of particles and fields. Experimental research towards a better understanding of what causes this acceleration — Dark Energy — have emerged in the form of Supernovae and galaxy surveys in the optical wavelengths and all-sky microwave maps. Theoretical efforts have generated a number of phenomenological models and proposed modifications of a stepping stone of physics knowledge — Einstein's general relativity theory of gravity. Dark Energy constitutes 3/4 of the total components of the universe today and unveiling its physical properties is one of the top goals of the contemporary scientific community. This talk presents an overview of the status of this field and the prospects for shedding light onto this problem with current and upcoming efforts.
