An Interacting Dark Energy Model for the Expansion History of the Universe

Authors: Micheal S. Berger, Hamed Shojaei

Report-no: IUHET-496

We explore a model of interacting dark energy where the dark energy density is related to the Hubble parameter, and the decay of the dark energy into matter occurs at a rate comparable to the current value of the Hubble parameter. We find this gives a good fit to the observational data supporting an accelerating Universe, and the model represents a possible alternative interpretation of the expansion history of the Universe.
