Prospects for probing the dark energy via supernova distance measurements
Abstract
Distance measurements to type Ia supernovae (SNe Ia) indicate that the Universe is accelerating and that twothirds of the critical energy density exists in a darkenergy component with negative pressure. Distance measurements to SNe Ia can be used to distinguish between different possibilities for the dark energy, and if it is an evolving scalar field, to reconstruct the scalarfield potential. We derive the reconstruction equations and address the feasibility of this approach by Monte Carlo simulation.
