Wide-field cosmic shear surveys

Abstract

We present the current status of cosmic shear based on all surveys done so far. Taken together, they cover more about 70 deg${}^2$ and concern more than 3 million galaxies with accurate shape measurement. Theoretical expectations, observational results and their cosmological interpretations are discussed in the framework of standard cosmology and CDM scenarios. The potentials of the next generation cosmic shear surveys are discussed.
