Cosmologie avec les distortions gravitationnelles
Cosmology with cosmic shear observations
Review article by Martin Kilbinger (CEA/Sap) in Reports on Progress in Physics
Martin Kilbinger 2015 Rep. Prog. Phys. 78 086901
Cosmic shear is the distortion of images of distant galaxies due to weak gravitational lensing by the large-scale structure in the Universe. Cosmic shear has become a powerful probe into the nature of dark matter and the origin of the current accelerated expansion of the Universe. We give an overview of weak-lensing measurements, and present the main observational cosmic-shear results since it was discovered 15 years ago, as well as the implications for cosmology. We then conclude with an outlook on the various future surveys and missions. Read more...
