Review: Cosmology from cosmic shear observations

Martin Kilbinger, CEA Saclay, Service d’Astrophysique (SAp), France

Find on this page general information and updates for my recent review article (arXiv:1411.0155) on cosmic shear, Reports on Progress in Physics 78 (2015) 086901 (ads link for two-column format).

Fig. 7 of the review article: The quantity $$\Sigma = \sigma_8 \left( \Omega_{\rm m}/0.3 \right)^\alpha$$ as function of publication year.

Updated figure!

02/2015: Added Stripe-82 and CFHTLenS peak counts

07/2015: Added DES-SV.

06/2016: Added DLS, two more CFHTLenS analyses, DES-SV peak counts, and KiDS-450.
08/2017: Added DES-Y1, and another KiDS-450 result.

12/2017: Added more KiDS-450 and DES-Y1 results (peak counts, lensing+clustering, density-split statistic).

In the video abstract of the article I talk about cosmic shear and the review for a broader audience.
