TL;DR: Euclid is a European Space Agency medium-class mission selected for launch in 2020 within the cosmic vision 2015-2025 program as discussed by the authors, which will explore the expansion history of the universe and the evolution of cosmic structures by measuring shapes and red-shift of galaxies as well as the distribution of clusters of galaxies over a large fraction of the sky.

TL;DR: This review is meant to provide a guide to the scientific themes that will underlie the activity of the group during the preparation of the Euclid mission and discusses five broad topics: dark energy and modified gravity, dark matter, initial conditions, basic assumptions and questions of methodology in the data analysis.

TL;DR: In this paper, the authors compute the quantity which is truly measured in a large galaxy survey, taking into account the effects coming from the fact that we actually observe galaxy redshifts and sky positions and not true spatial positions.

TL;DR: In this article, the authors derived an expression for the luminosity distance in a perturbed Friedmann universe and derived the correlation function and the power spectrum of the LDM fluctuations and expressed them in terms of the initial spectrum of a Bardeen potential.

TL;DR: In this paper, the future potential of the LISA mission in the area of fundamental physics is further delineated and sharpen by identifying the sources that are currently expected to provide the principal contribution to our knowledge, and the areas that need further development.
