*The Accelerating Universe and Vacuum Energy*

During his senior project, Daniel Pfeffer will investigate the acceleration of the Universe. He will explore whether or not it is possible to screen the effect of a large vacuum energy and give rise the amount of acceleration currently observed by supernovae and other probes. …Read more.

*Axion Electrodynamics*

Axions were introduced in particle physics in the 1970s to explain CP violation in the standard model. Subsequently axions have become a leading candidate for dark matter in Cosmology. …Read more.
