Abstract
This review surveys the signatures of dark energy on large-scale structures (LSS) at low redshift, focusing on observables relying on the evolution of matter perturbations, i.e. on the growth of structures. We discuss in particular galaxy clustering, weak-gravitational lensing by LSS, also called cosmic-shear, and Lyman- $\alpha$ forest, which respectively describe the 3D, 2D, and 1D power spectrum of matter density fluctuations. We illustrate some example of data analysis for each these observables.

What is OpenURL?

The OpenURL standard is a protocol for transmission of metadata describing the resource that you wish to access. An OpenURL link contains article metadata and directs it to the OpenURL server of your choice. The OpenURL server can provide access to the resource and also offer complementary services (specific search engine, export of references...). The OpenURL link can be generated by different means.

If your librarian has set up your subscription with an OpenURL resolver, OpenURL links appear automatically on the abstract pages.
You can define your own OpenURL resolver with your EDPS Account. In this case your choice will be given priority over that of your library.
You can use an add-on for your browser (Firefox or I.E.) to display OpenURL links on a page (see http://www.openly.com/openurlref/). You should disable this module if you wish to use the OpenURL server that you or your library have defined.
