Abstract

Understanding the nature of the dark energy responsible of the apparent acceleration of the Universe is one of the most challenging questions of our modern Cosmology and Fundamental Physics. On both side of the Atlantic a great deal of effort has been spent to design and optimize space missions able to probe the nature of this dark energy. These missions generally use two or three of the major cosmological probes: Baryonic Acoustic Oscillation (BAO), Weak Lensing (WL) and Type Ia Supernovae (SNe). Many of the proposed missions concept rely on having different instruments sharing a common optical interface and thus leading to a highly complex system. By adopting a different conceptual approach we studied a fully integrated optical design yielding to a simple and more cost effective mission. The survey strategy will also benefit from this design which offers a better time sharing between the different probes.
