Description
The main Euclid mission objective is to map the geometry of the dark Universe by investigating the distance-redshift relationship and the evolution of cosmic structures.
The Euclid project is part of ESA’s program Cosmic Vision program with its launch planned for 2020.
We will describe the potential of Euclid for the investigation of the Dark universe with respect to the current and future experiments.
The main aspects of the survey observational strategy relevant for cosmology will be discussed, including the wide sky coverage for the two instruments VIS (Visible Instrument) and NISP (Near Infrared Spectro-Photometer) and small scale aspects.
Particular attention will be posed on the NISP instrument, operating as a photometer and spectrometer, and on its components.
The architecture of the instrument, expected performance, and technological key challenges will be presented, showing how scientific goals will be met.
Finally, the implications for the study of dark energy and gravity from the Euclid measurements of the gravitational weak lensing and of the galaxy clustering (baryonic acoustic oscillations and redshift space distortions) will be discussed.
